Check Digit Verification of cas no

The CAS Registry Mumber 1277170-53-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,7,1,7 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1277170-53:
(9*1)+(8*2)+(7*7)+(6*7)+(5*1)+(4*7)+(3*0)+(2*5)+(1*3)=162
162 % 10 = 2
So 1277170-53-2 is a valid CAS Registry Number.

[[(tert-Butyl)dimethylsilyl]oxy]-methylGroup for sulfur protection

Wang, Lihong,Clive, Derrick L. J.

supporting information; experimental part, p. 1734 - 1737 (2011/06/09)

Aromatic and aliphatic thiols can be protected by reaction with t-BuMe 2SiOCH2Cl in DMF in the presence of a base (2,6-lutidine or proton sponge); the resulting t-BuMe2SiOCH2SR or t-BuMe2SiOCH2SAr are deprotected by sequential treatment with Bu4NF and I2 to give symmetrical disulfides. Another mode of deprotection involves reaction with a sulfenyl chloride; this process gives an unsymmetrical disulfide and was examined with Me(CH2) 11SCH2OSiMe2Bu-t and three sulfenyl chlorides.
