Check Digit Verification of cas no

The CAS Registry Mumber 934562-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,5,6 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 934562-80:
(8*9)+(7*3)+(6*4)+(5*5)+(4*6)+(3*2)+(2*8)+(1*0)=188
188 % 10 = 8
So 934562-80-8 is a valid CAS Registry Number.

Polymer-supported (2,6-dichloro-4-alkoxyphenyl)(2,4-dichlorophenyl) methanol: A new linker for solid-phase organic synthesis

Kurosu, Michio,Biswas, Kallolmay,Crick, Dean C.

, p. 1141 - 1144 (2007/10/03)

(Chemical Equation Presented) An acid and base stable hydroxytetrachlorodiphenylmethyl (HTPM) linker is developed for polymer-supported organic synthesis. The linkers reported here are utilized for loading carboxylic acids, amines, alcohols, and phenols, and are stable to Bronsted and Lewis acids, Bronsted bases, and a wide variety of nucleophiles. However, the HTPM linkers can conveniently be cleaved by the solvolytic displacement reactions with 20% TFA.
