Check Digit Verification of cas no

The CAS Registry Mumber 957375-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,3,7 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 957375-99:
(8*9)+(7*5)+(6*7)+(5*3)+(4*7)+(3*5)+(2*9)+(1*9)=234
234 % 10 = 4
So 957375-99-4 is a valid CAS Registry Number.

Synthesis of 5-methyl-4-oxo-2-(coumarin-3-yl)-N-aryl-3,4-dihydrothieno[2,3- d]-pyrimidine-6-carboxamides

Kovalenko, Sergiy M.,Vlasov, Sergiy V.,Chernykh, Valentin P.

, p. 341 - 346 (2008/02/12)

Possible approaches to synthesis of 5-methyl-4-oxo-2- (coumarin-3-yl)-N- aryl-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxamides 4 have been discussed. It is shown that the preferable approach is cyclization of 2-iminocoumarin-3- carboxamides 1, utilizing
