Check Digit Verification of cas no

The CAS Registry Mumber 428859-12-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,8,8,5 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 428859-12:
(8*4)+(7*2)+(6*8)+(5*8)+(4*5)+(3*9)+(2*1)+(1*2)=185
185 % 10 = 5
So 428859-12-5 is a valid CAS Registry Number.

Synthesis of trichloromethylpyrimidines and trichloromethylpyrimido [4,5-d]pyrimidines from alkyl 2-(diaminomethylidene)-3-oxobutyrates and trichloroacetonitrile

Voronkova,Komkov,Dorokhov

, p. 351 - 355 (2009)

Heterocyclization of alkyl 2-(diaminomethylidene)-3-oxobutyrates with trichloroacetonitrile yields alkyl 4-mino-6-methyl-2-trichloromethylpyrimidine- 5-carboxylates. The latter compounds react with aryl isocyanates to produce the corresponding pyrimidinyl
