Check Digit Verification of cas no

The CAS Registry Mumber 253152-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,1,5 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 253152-07:
(8*2)+(7*5)+(6*3)+(5*1)+(4*5)+(3*2)+(2*0)+(1*7)=107
107 % 10 = 7
So 253152-07-7 is a valid CAS Registry Number.

Synthesis of cyclic ethers and allylic sulfides by rearrangement of phenylsulfanyl substituted 1,n-diols with toluene-p-sulfonic acid and with toluene-p-sulfonyl chloride

Djakovitch, Laurent,Eames, Jason,Fox, David J.,Sansbury, Francis H.,Warren, Stuart

, p. 2771 - 2782 (2007/10/03)

Rearrangement of a series of l,n-diols (n = 2 to 12), with a PhS-group adjacent to one OH group, under two sets of conditions gives single compounds in excellent yield drawn for four possible classes of products. The effect of the chain length helps in the understanding of the different cyclisation modes and the mechanism of the rearrangements. The Royal Society of Chemistry 1999.
