Check Digit Verification of cas no

The CAS Registry Mumber 70123-49-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,2 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 70123-49:
(7*7)+(6*0)+(5*1)+(4*2)+(3*3)+(2*4)+(1*9)=88
88 % 10 = 8
So 70123-49-8 is a valid CAS Registry Number.

N-(2,2,2-trichloroethylidene)- and N-(1-hydroxy-2,2,2-trichloroethyl) amides in C-amidoalkylation reaction of functionally-substituted aromatic compounds

Aizina,Rozentsweig,Levkovskaya,Rozentsweig,Mirskova

, p. 235 - 238 (2002)

A reaction with phenol and pyrocatechol of N-(2,2,2-trichloroethylidene)arenesulfonyl-, ethoxycarbonylamides and 1-hydroxy-substituted N-(2,2,2-trichloroethyl)amides of arenesulfonic, carbamic, and acetic acids in the presence of oleum or in sulfuric acid provided the corresponding (1-amido-2,2,2-trichloroethyl)-substituted phenols. N-(2,2,2-Trichloroethylidene)-4-chlorobenzenesulfonamide reacted with salicylamide in the presence of oleum to afford 3-aminocarbonyl-4-[2,2,2-trichloro-1-(4-chlorobenzene-sulfonamido)ethyl]benzene whereas the 1-hydroxy-2,2,2-trichloroethylamides of the acetic, carbamic, and arenesulfonic acids did not enter into such reactions.
