Check Digit Verification of cas no

The CAS Registry Mumber 1164467-30-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,4,4,6 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1164467-30:
(9*1)+(8*1)+(7*6)+(6*4)+(5*4)+(4*6)+(3*7)+(2*3)+(1*0)=154
154 % 10 = 4
So 1164467-30-4 is a valid CAS Registry Number.

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.
