Check Digit Verification of cas no

The CAS Registry Mumber 87243-48-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,4 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87243-48:
(7*8)+(6*7)+(5*2)+(4*4)+(3*3)+(2*4)+(1*8)=149
149 % 10 = 9
So 87243-48-9 is a valid CAS Registry Number.

ACETALS OF LACTAMS AND ACID AMIDES. 47.* INVESTIGATION OF THE BEHAVIOR OF SUBSTITUTED 6-(β-DIMETHYLAMINO)VINYL-4-PYRIMIDINONES IN ACID MEDIA. SYNTHESIS OF 3-CYANO-4-ANILINO-5-FORMYL-2-PYRIDONE AND 3-CHLORO-4-CYANOBENZONAPHTHYRIDINE

Yalysheva, N.Z.,Solov'eva, N.P.,Chistyakov, V.V.,Sheinker, Yu.N.,Granik, V.G.

, p. 909 - 914 (2007/10/02)

The hydrolysis of 1-substituted 5-cyano-6-(β-dimethylamino)vinyl-4-pyrimidinones in acidic media was studied.It was shown that the 1-benzyl derivative is converted to a mixture of α-cyano-4β-benzylamino-crotonamide and 3-cyano- and 3-carbamido-4-benzyl-amino-2-pyridones.The principal product in the hydrolysis of the 1-phenyl derivative is 3-cyano-4-anilino-5-formyl-2-pyridone.Cyclization of the latter by heating in phosphorus oxychloride leads to 3-chloro-4-cyanobenzonaphthyridine.

ACETALS OF LACTAMS AND ACID AMIDES. 40. SYNTHESIS AND HYDROLYTIC CLEAVAGE OF ONE-RING AND TWO-RING DERIVATIVES OF 4-PYRIMIDINONE

Granik, V. G.,Grizik, S. I.,Kiselev, S. S.,Chistyakov, V. V.,Anisimova, O. S.,Solov'eva, N. P.

The reaction of 1-benzyl-5-cyano-6-dimethylaminomethylene-1,6-dihydro-4-pyrimidinone with acid leads to 5-benzyl-1,2,7,8-tetrahydropyridopyrimidine-1,8-dione, whereas the reaction with ammonia leads to a mixture of 3-cyano-4-benzylamino-2-pyridone

ACETALS OF LACTAMS AND ACID AMIDES. 38. SYNTHESIS OF PYRIMIDINE AND PYRIDINE DERIVATIVES ON THE BASIS OF THE REACTION OF ENAMINO AMIDES WITH AMIDE ACETALS

Granik, V. G.,Kaimanakova, S. I.

, p. 657 - 661 (2007/10/02)

Derivatives of 1-benzyl-4-pyrimidinones and 1-benzyl-6-pyrimidinones were synthesized by the reaction of α-cyano-β-N-benzylaminocrotonamide and α-cyano-β-aminocrotonic acid N-benzylamine with dimethylformamide diethylacetal.When 1-benzyl-5-cyano-6-(β-dimethylamino)vinyl-1,6-dihydro-4-pyrimidinone is heated in an alkaline medium, it is converted to 3-cyano-4-benzylamino-2-pyridone, from which a pyridopyrimidine derivative was synthesized.When 1-benzyl-5-cyano-4-(β-dimethylamino)vinyl-1,6-dihydro-6-pyrimidinone is heated in alkaline solution, it is converted to α-cyano-β-hydroxycrotonic acid N-benzylamide.
