Check Digit Verification of cas no

The CAS Registry Mumber 160971-59-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,9,7 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 160971-59:
(8*1)+(7*6)+(6*0)+(5*9)+(4*7)+(3*1)+(2*5)+(1*9)=145
145 % 10 = 5
So 160971-59-5 is a valid CAS Registry Number.

Activation of methylphosphonates and their thio- and seleno congeners with 1,3,5-triazinyl morpholinium salts. selenono-selenolo isomerization

Wozniak, Lucyna A.,Gra, Marcin,Kaminski, Zbigniew,Stec, Wojciech J.

, p. 1076 - 1081 (2008)

The stereospecific activation of nucleoside 3'-O-methylphosphonoselenoates (1) with N-methyl-N-4,6-dimethoxy-1,3,5-triazinyl-yl morpholinium chloride resulted in formation of both O-activated (5) and Se-activated (6) 1,3,5-triazin-yl esters.
