Check Digit Verification of cas no

The CAS Registry Mumber 903875-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,8,7 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 903875-80:
(8*9)+(7*0)+(6*3)+(5*8)+(4*7)+(3*5)+(2*8)+(1*0)=189
189 % 10 = 9
So 903875-80-9 is a valid CAS Registry Number.

Intermolecular aza-Wittig reaction: One-step synthesis of pyrazolo[1,5-a]pyrimidine and imidazo[1,2-b]pyrazole derivatives

Barsy, Magda A.,El-Rady, Eman A.

, p. 523 - 526 (2006)

Pyrazolo[1,5-a]pyrimidine and imidazo[1,2-b]pyrazole derivatives were synthesized via intermolecular aza-Wittig reaction of 5- (triphenylphosphoranylideneamino)-3-phenylpyrazole 3 derived from 5-amino-3-phenylpyrazole with some selected α-chloroketones.
