Check Digit Verification of cas no

The CAS Registry Mumber 20955-75-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,5 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20955-75:
(7*2)+(6*0)+(5*9)+(4*5)+(3*5)+(2*7)+(1*5)=113
113 % 10 = 3
So 20955-75-3 is a valid CAS Registry Number.

New and general nitrogen heterocycle synthesis: Use of heteropoly acids as a heterogeneous recyclable catalyst

Hekmatshoar, Rahim,Sadjadi, Sodeh,Sadjadi, Samaheh,Heravi, Majid M.,Beheshtiha, Yahya S.,Bamoharram, Fatemeh F.

, p. 1708 - 1716 (2010)

An efficient synthetic method of six-and five-member nitrogen heterocyclic compounds was developed. Nitrogen heterocyclic compounds were prepared by condensation of the-dicarbonyl compounds with the corresponding-or-amino alcohols, subsequent cyclization, and spontaneous aromatization in the presence of a catalytic amount of Keggin-type heteropoly acids under very mild conditions.
