Check Digit Verification of cas no
The CAS Registry Mumber 98070-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,7 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98070-39:
(7*9)+(6*8)+(5*0)+(4*7)+(3*0)+(2*3)+(1*9)=154
154 % 10 = 4
So 98070-39-4 is a valid CAS Registry Number.

(2,6-Dichloro-4-alkoxyphenyl)-(2,4-dichlorophenyl)methyl trichloroacetimidates: Protection of alcohols and carboxylic acids in solution or on polymer support
Kurosu, Michio,Li, Kai
experimental part, p. 3633 - 3641 (2010/03/05)
(2,6-Dichloro-4-methoxyphenyl)-(2,4-dichlorophenyl)-methyl trichloroacetimidate can be efficiently activated by TMSOTf (10-100 mol%) to react with alcohols and carboxylic acids. Under these conditions a wide variety of alcohols can be transformed into the corresponding ethers in excellent yields with a slight excess of the trichloroacetimidate. The resulting ethers are not susceptible to typical deprotection conditions for benzyl and 4-methoxybenzyl ether groups, however, they can be conveniently deprotected by treatment with 30-50% trifluoroacetic acid in dichloromethane. Polymer-bound (2,6-dichloro-4-alkoxyphenyl)-(2,4-dichlorophenyl)methyl trichloroacetimidate is useful for immobilization of alcohols and carboxylic acids.
