Check Digit Verification of cas no

The CAS Registry Mumber 84941-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,4 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84941-18:
(7*8)+(6*4)+(5*9)+(4*4)+(3*1)+(2*1)+(1*8)=154
154 % 10 = 4
So 84941-18-4 is a valid CAS Registry Number.

REACTION OF 3,4-DICYANO-5-AMINOPYRAZOLE WITH ETHYL ORTHOFORMATEI730

Bulychev, Yu.N.,Korbukh, I.A.,Preobrazhenskaya, M.N.

, p. 1302 - 1305 (1982)

The condensation of 3,4-dicyano-5-aminopyrazole with ethyl orthoformate was studied.Under severe conditions (150 deg C) the principal reaction product is N-ethyl-3,4-dicyano-5-ethoxymethylaminopyrazole.Alkylation of the pyrazole ring does not occur at 100 deg C, but 3,4-dicyano-5-ethoxymethyleneaminopyrazole is formed.Isomeric 1-and 2-ethyl-4-aminopyrazolopyrimidine-3-carboxylic acid methyl imino esters were obtained by the action of a methanol solution of ammonia on the principal reaction product.This constitutes evidence that N-ethyl-3,4-dicyano-5-ethoxymethyleneaminopyrazole is a mixture of 1- and 2-ethyl- 3,4-dicyano-5-ethoxymethyleneaminopyrazoles.
