Check Digit Verification of cas no

The CAS Registry Mumber 27808-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,8,0 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27808-19:
(7*2)+(6*7)+(5*8)+(4*0)+(3*8)+(2*1)+(1*9)=131
131 % 10 = 1
So 27808-19-1 is a valid CAS Registry Number.

Regioselective synthesis of silylated pyrazolines and indazolines by reaction of pyrazolium and indazolium salts with silyllithium reagents

Gonzalez-Nogal, Ana M.,Calle, Mariola,Calvo, Luis A.,Cuadrado, Purificacion,Gonzalez-Ortega, Alfonso

, p. 4663 - 4669 (2005)

Pyrazolium salts react with dimethylphenylsilyl- and tert- butyldiphenylsilyllithium to give, in general, only one of the two possible 5-silyl-3-pyrazolines. On the other hand, indazolium and isoindazolium salts lead to 3-silylindazolines and occasionally
