Check Digit Verification of cas no
The CAS Registry Mumber 87573-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,7 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87573-91:
(7*8)+(6*7)+(5*5)+(4*7)+(3*3)+(2*9)+(1*1)=179
179 % 10 = 9
So 87573-91-9 is a valid CAS Registry Number.

Syntheses and Reactions of Some 5-Vinyl- and 5-Ethynylpyrimidines
Benneche, Tore,Undheim, Kjell
, p. 235 - 240 (2007/10/02)
5-β,β-Dichlorovinyl- and 5-α-chlorovinylpyrimidines have been prepared from 5-acetyl-2-methylthiopyrimidines.HCl elimination from the 5-α-chlorovinyl derivatives yields the 5-ethynyl analogues.Peracid or chlorine oxidation of the sulfides yields the sulfones which may be hydrolyzed to the corresponding lactams.The reaction paths are discussed.
