Check Digit Verification of cas no
The CAS Registry Mumber 2003-92-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,0 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2003-92:
(6*2)+(5*0)+(4*0)+(3*3)+(2*9)+(1*2)=41
41 % 10 = 1
So 2003-92-1 is a valid CAS Registry Number.

Silylating Disulfides and Thiols with Hydrosilicones Catalyzed by B(C6F5)3
Brook, Michael A.,Liao, Mengchen,Zheng, Sijia

Hydrosilanes and silicones, catalyzed with B(C6F5)3, may be used to silylate thiols or cleave disulfides giving silyl thio ethers. Alcohols were found to react faster than thiols or disulfides, while alkoxysilanes (the Piers-Rubinsztajn reaction) were slower such that the overall order of reactivity was found to be HO>HS>SS>SiOEt. The resulting silane and silicone-protected thio ethers produced from the sulfur-based functional groups could be cleaved to thiols using alcohols or mild acid with rates that depend on the steric bulk of the siloxane.
