Check Digit Verification of cas no
The CAS Registry Mumber 84719-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,7,1 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 84719-31:
(7*8)+(6*4)+(5*7)+(4*1)+(3*9)+(2*3)+(1*1)=153
153 % 10 = 3
So 84719-31-3 is a valid CAS Registry Number.

Demethylation of methoxypyridines with sodium trimethylsilanethiolate
Shiao, Min-Jen,Ku, Wei-Shen,Hwu, Jih Ru
, p. 323 - 328 (2007/10/02)
Demethylation of methoxypyridines was accomplished in 55-87percent yield by use of ca. 1.5-2.5 equivalents of NaSSiMe3 in 1,3-dimethyl-2-imidazolidinone at 120-180 deg C.This method was found applicable to a methoxyquinoline and methoxypyridines containing a second substituent, such as Cl, OMe, and COOMe.
