Check Digit Verification of cas no

The CAS Registry Mumber 105866-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,8,6 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105866-95:
(8*1)+(7*0)+(6*5)+(5*8)+(4*6)+(3*6)+(2*9)+(1*5)=143
143 % 10 = 3
So 105866-95-3 is a valid CAS Registry Number.

DI-TERT-BUTYLMETHYLSILYL (DTBMS) TRIFLUOROMETHANESULFONATE. PREPARATION AND SYNTHETIC APPLICATIONS OF DTBMS ESTERS AND ENOL ETHERS

Bhide, Rajeev S.,Levison, Bruce S.,Sharma, Ram B.,Ghosh, Subrata,Salomon, Robert G.

, p. 671 - 674 (2007/10/02)

DTBMS triflate, readily available from dichloromethylsilane, provides carboxylic esters which resist reduction by hydridoaluminate or acid catalyzed hydrolysis, and vinylogous esters ( enol ethers of hydroxymethylene ketones ) which resist 1,4-addition of methyllithium.
