Check Digit Verification of cas no

The CAS Registry Mumber 74032-41-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,3 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74032-41:
(7*7)+(6*4)+(5*0)+(4*3)+(3*2)+(2*4)+(1*1)=100
100 % 10 = 0
So 74032-41-0 is a valid CAS Registry Number.

A New and Convenient Synthetic Method for Cyclopropyl Phenyl Sulfides

Tanaka, Kazuhiko,Uneme, Hideki,Matsui, Shuichi,Kaji, Aritsune

, p. 2965 - 2972 (2007/10/02)

The reactions of a variety of 1,3-bis(phenylthio)propanes with butyllithium have been shown to produce cyclopropyl phenyl sulfides in good to high yields.A new and convenient in situ preparation of 1-lithiocyclopropyl phenyl sulfide can be readily carried out by treating 1,3-bis(phenylthio)propane with 2 equiv. of butyllithium at 0 degC in THF.The reaction with electrophiles proceeds in good yield.O-Aryl and O-alkyl S-cyclopropyl dithiocarbonates also can be prepared in good yields. 1,2-Bis(phenylthio)ethane was converted to phenyl vinyl sulfide on treatment with butyllithium, while 1,4-bis(phenylthio)butane was recovered unchanged by a similar treatment.
