Check Digit Verification of cas no

The CAS Registry Mumber 1639808-98-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,9,8,0 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1639808-98:
(9*1)+(8*6)+(7*3)+(6*9)+(5*8)+(4*0)+(3*8)+(2*9)+(1*8)=222
222 % 10 = 2
So 1639808-98-2 is a valid CAS Registry Number.

Synthesis of polysubstituted pyrazolo[3,4-b]pyridine-3-carbohydrazide and pyrazolo[3,4-d]pyridazine derivatives

Bhavsar, Dinesh C.,Nikam, Prashant S.,Gangurde, Sachin A.,Toche, Raghunath B.

, p. 635 - 641 (2014/06/10)

5-Amino-4-formyl pyrazole carboxylate gave facile reactions with malononitrile, hydrazine, and ketones in the presence of piperidine furnished substituted pyrazolo[3,4-b]pyridines and pyrazolo[3,4-b]quinolones. The pyridazine sulfonamides were obtained by the reaction of 5-chloro 4-formyl pyrazole carboxylate with sulfonamide derivatives.
