74390-79-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74390-79-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,9 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74390-79:
(7*7)+(6*4)+(5*3)+(4*9)+(3*0)+(2*7)+(1*9)=147
147 % 10 = 7
So 74390-79-7 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)

(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.

High-throughput synthesis of substituted hydrazine derivatives
