Check Digit Verification of cas no

The CAS Registry Mumber 1011625-29-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,1,6,2 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1011625-29:
(9*1)+(8*0)+(7*1)+(6*1)+(5*6)+(4*2)+(3*5)+(2*2)+(1*9)=88
88 % 10 = 8
So 1011625-29-8 is a valid CAS Registry Number.

Synthesis and properties of 4-(3-aminothieno-[2,3-b]pyridin-2-yl)coumarins

Gorelov,Bondarenko,Frasinyuk

, p. 955 - 962 (2013/01/15)

Substituted 4-[(3-cyanopyridin-2-yl)thiomethyl]coumarins have been synthesized by the alkylation of 2-mercapto-4,6-dimethylnicotinonitrile with 4-chloromethylcoumarins. Substituted 4-(3-amino-thieno[2,3-b]pyridin-2-yl) coumarins have been obtained by a subsequent intramolecular condensation of the methylene and cyano groups. 6H-Chromeno[4,3-d]thieno[3,2-b:5,4-b']dipyridin-6- ones were isolated as a result of the interaction of these compounds with aldehydes, and their aminomethyl derivatives were synthesized.
