Check Digit Verification of cas no

The CAS Registry Mumber 180537-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,5,3 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180537-85:
(8*1)+(7*8)+(6*0)+(5*5)+(4*3)+(3*7)+(2*8)+(1*5)=143
143 % 10 = 3
So 180537-85-3 is a valid CAS Registry Number.

The use of aliphatic aldehydes for the synthesis of 4-alkyl-6-amino-3,5-dicyanopyridine-2(1h)-thiones

Frolova,Zav'yalova,Litvinov

, p. 893 - 897 (1996)

The condensation of aliphatic aldehydes with malononitrile and cyanothioacetamide gives 4-alkyl-2,6-diamino-3,5-dicyano-4H-thiopyrans which recyclize into 4-alkyl-6-amino-3,5-dicyanopyridine-2(1H)-thiones. The latter are easily S-alkylated with α-haloacetonitriles and α-haloacetophenones.
