Check Digit Verification of cas no
The CAS Registry Mumber 75458-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,5 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75458-20:
(7*7)+(6*5)+(5*4)+(4*5)+(3*8)+(2*2)+(1*0)=147
147 % 10 = 7
So 75458-20-7 is a valid CAS Registry Number.

Tert-Alkyl chlorides 5 are prepared in good yield from the corresponding alcohols 1 in a facile two step synthesis.The method involves treatment of the corresponding crude oxalyl monochloride alkyl ester 2 with N-hydroxy-pyridine-2-thione sodium salt 3 in tetrachloromethane at reflux to give the bright yellow N-(alkoxyoxalyloxy)pyridine-2-thiones 4 which undergo decomposition to the chlorides 5 in good yield.The reaction is conveniently monitored by the loss of colour from the mixed anhydride.
