Check Digit Verification of cas no

The CAS Registry Mumber 55704-82-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,7,0 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55704-82:
(7*5)+(6*5)+(5*7)+(4*0)+(3*4)+(2*8)+(1*2)=130
130 % 10 = 0
So 55704-82-0 is a valid CAS Registry Number.

REACTIONS OF CHLORINE MONOFLUORIDE. IV. ADDITION OF CHLORINE MONOFLUORIDE TO HALOGEN-SUBSTITUTED ALKENES

Boguslavskaya, L. S.,Chuvatkin, N. N.,Panteleeva, I. Yu.

, p. 1832 - 1842 (2007/10/02)

The reactions of chlorine monofluoride with halogenoethylenes (1,1-dichloro-, 1,2-dichloro-, trichloro-, and tetrachloroethylenes) and halogenopropenes ( 3-bromo-, 3,3,3-trichloro-, E- and Z-1,3-dichloro-, 3-chloro-2-methyl-, and perfluoropropenes) were investigated in inert solvents in the presence of ethyl acetate as external nucleophile.In all cases chloroacyloxy adducts were isolated and identified in addition to the chlorofluorination products, and this indicates an electrophilic mechanism for the chlorofluorination of polyhalogenoalkenes.Methyl chloromaleate, chlorofumarate, chlorofluoroethylenedicarboxylate, α,β-difluoroacrylate, and perfluoromethacrylate in anhydrous hydrogen fluoride form the corresponding chlorofluoro adducts with satisfactory yields, whereas the reaction takes place with difficulty in inert solvents.
