Check Digit Verification of cas no

The CAS Registry Mumber 439946-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,9,4 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 439946-22:
(8*4)+(7*3)+(6*9)+(5*9)+(4*4)+(3*6)+(2*2)+(1*2)=192
192 % 10 = 2
So 439946-22-2 is a valid CAS Registry Number.

Anilinomethylidene derivatives of cyclic 1,3-dicarbonyl compounds in the synthesis of new sulfur-containing pyridines and quinolines

Dotsenko,Krivokolysko,Chernega,Litvinov

, p. 1556 - 1561 (2007/10/03)

Simple methods for the synthesis of previously unknown sulfur-containing pyridin-2-ones and 5,6,7,8-tetrahydroquinolines from cyanothioacetamide and anilinomethylidene derivatives of cyclic 1,3-dicarbonyl compounds were developed. Structures and chemical transformations of compounds obtained were studied.
