Check Digit Verification of cas no

The CAS Registry Mumber 958222-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,8,2,2 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 958222-95:
(8*9)+(7*5)+(6*8)+(5*2)+(4*2)+(3*2)+(2*9)+(1*5)=202
202 % 10 = 2
So 958222-95-2 is a valid CAS Registry Number.

Chemoselective synthesis of thieno[3,2-c][1,8]naphthyridin-4(5H)-ones by tandem cyclization

Majumdar, Krishna C.,Rafique-ul-Islam

, p. 87 - 92 (2007/10/03)

A number of the thieno[3,2-c][1,8]-naphthyridin-4(5H)-ones are chemoselectively synthesized from 4-(4′-aryloxybut-2′-ynylthio)-1- phenyl-1,8-naphthyridin-2(1H)-ones in 82-90% yield by the formation of sulfoxide, followed by [2,3] and [3,3]sigmatropic rear
