Check Digit Verification of cas no

The CAS Registry Mumber 303013-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,0,1 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 303013-99:
(8*3)+(7*0)+(6*3)+(5*0)+(4*1)+(3*3)+(2*9)+(1*9)=82
82 % 10 = 2
So 303013-99-2 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 (2002)

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.
