Check Digit Verification of cas no

The CAS Registry Mumber 70153-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,5 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 70153-23:
(7*7)+(6*0)+(5*1)+(4*5)+(3*3)+(2*2)+(1*3)=90
90 % 10 = 0
So 70153-23-0 is a valid CAS Registry Number.

Trimethylsilyl esters, AcOTMS, BzOTMS, TCAOTMS, etc., are inexpensive and chemically stable reagents that pose a negligible environmental hazard. Such compounds prove to serve as efficient dualpurpose reagents to respectively achieve acylation and trimethylsilylation of alcohols under acidic or basic conditions. Herein, a detailed study on protection of various substrates and new methodological investigations is described.
