Check Digit Verification of cas no
The CAS Registry Mumber 743414-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,3,4,1 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 743414-22:
(8*7)+(7*4)+(6*3)+(5*4)+(4*1)+(3*4)+(2*2)+(1*2)=144
144 % 10 = 4
So 743414-22-4 is a valid CAS Registry Number.

An efficient synthesis of LY544344?HCl: A prodrug of mGluR2 agonist LY354740
Coffey, D. Scott,Hawk, Mai Khanh,Pedersen, Steven W.,Vaid, Radhe K.
, p. 7299 - 7302 (2005)
LY544344?HCl was efficiently prepared in two steps from LY354740. The key step highlighted the in situ masking of the carboxylic acid groups as trimethylsilyl esters to facilitate an effective acylation reaction.
