Check Digit Verification of cas no

The CAS Registry Mumber 1058676-79-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,8,6,7 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1058676-79:
(9*1)+(8*0)+(7*5)+(6*8)+(5*6)+(4*7)+(3*6)+(2*7)+(1*9)=191
191 % 10 = 1
So 1058676-79-1 is a valid CAS Registry Number.

Poorly reactive 5-piperazin-1-yl-1,3,4-thiadiazol-2-amines rendered as valid substrates for Groebke-Blackburn type multi-component reaction with aldehydes and isocyanides using TMSCl as a promoter

Krasavin, Mikhail,Tsirulnikov, Sergey,Nikulnikov, Mikhail,Kysil, Volodymyr,Ivachtchenko, Alexandre

, p. 5241 - 5243 (2008/12/22)

N-Substituted 5-piperazin-1-yl-1,3,4-thiadiazol-2-amines that fail to undergo Groebke-Blackburn type MCR with aldehydes and isocyanides provide fair to good yields of the respective 2-piperazin-1-ylimidazo[2,1-b][1,3,4]thiadiazoles when such reaction is promoted by an equimolar quantity of trimethylsilyl chloride in aprotic medium. These findings further extend the utility of TMSCl as the isocyanide-based MCR promoter, and also demonstrate that this silicon Lewis acid is the actual promoter of the reaction.
