Check Digit Verification of cas no

The CAS Registry Mumber 99853-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,5 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99853-81:
(7*9)+(6*9)+(5*8)+(4*5)+(3*3)+(2*8)+(1*1)=203
203 % 10 = 3
So 99853-81-3 is a valid CAS Registry Number.

Synthesis and heterocyclization of osazones of carbonyl-substituted glyoxals

Guseinov,Yudina,Klimentova

, p. 167 - 170 (1998)

Enolates of α-chloro-β-oxoaldehydes react with arylhydrazines in the presence of acetic acid, forming osazones of carbonyl-substituted glyoxals. The same osazones are obtained by the reaction of β-oxo-α-chlorenamines with arylhydrazines. Under conditions
