Check Digit Verification of cas no

The CAS Registry Mumber 153123-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,1,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 153123-09:
(8*1)+(7*5)+(6*3)+(5*1)+(4*2)+(3*3)+(2*0)+(1*9)=92
92 % 10 = 2
So 153123-09-2 is a valid CAS Registry Number.

Asymmetric chemical oxidations of aryl and alkyl 2-(trimethylsilyl)ethyl sulfides

Schwan,Pippert

, p. 131 - 138 (1995)

A collection of aryl and alkyl 2-(trimethylsilyl)methyl sulfides have been converted to their respective sulfoxides by four different asymmetric oxidizing agents. The chemical yields range from 44-98% while the enantiomeric excesses range from 0-89%. The

Convenient Preparation of Optically Pure Propargylic Alcohols Using 2-(Trimethylsilyl)vinyl Sulfoxide As A Novel Chiral Synthon

Kusuda, Shinya,Kawamura, Kiyoshi,Ueno, Yoshio,Toru, Takeshi

, p. 6587 - 6590 (2007/10/02)

Both enentiomers of optically pure propargylic alcohols are conveniently prepared by the reaction of α-vinyl anion of 2-(trimethylsilyl)vinyl p-tolyl sulfoxide with aldehydes and subsequent either desilylsulfination or thermal elimination of the sulfinyl group.
