Check Digit Verification of cas no

The CAS Registry Mumber 680190-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,0,1,9 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 680190-67:
(8*6)+(7*8)+(6*0)+(5*1)+(4*9)+(3*0)+(2*6)+(1*7)=164
164 % 10 = 4
So 680190-67-4 is a valid CAS Registry Number.

4-Functionally substituted 3-heterylpyrazoles: XII. 4-Chlorothieno[2,3-c] pyrazole-5-carbonyl chlorides

Bratenko,Chornous,Vovk

, p. 893 - 896 (2007/10/03)

3-(4-Pyrazolyl)acrylic acids reacted with excess thionyl chloride in the presence of benzyltri-ethylammonium chloride affording 4-chlorothieno[2,3-c] pyrazole-5-carbonyl chlorides which were converted into the corresponding acids, esters, and amides.
