Check Digit Verification of cas no

The CAS Registry Mumber 118083-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,0,8 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118083-48:
(8*1)+(7*1)+(6*8)+(5*0)+(4*8)+(3*3)+(2*4)+(1*8)=120
120 % 10 = 0
So 118083-48-0 is a valid CAS Registry Number.

Modern Friedel-Crafts chemistry. XVI. Sterically controlled cyclodehydration of selected arylalkanols

Khawaga, A. M. El-,Zohry, M. F. El-,Wahab, A. A. Abdel-,Khalaf, A. A.

, p. 1051 - 1055 (2007/10/02)

The cyclodehydration of three selected arylalkanols, namely 1,3-diphenyl-3-pentanol (I), 1,1,4-triphenyl-2methyl-1-butanol (II) and 1,1,4-triphenyl-2-methyl-2-butanol (III) with Friedel-Crafts catalysts was investigated.A reasonable interpretation of the reaction products was suggested, steric hindrance was found to have major influence on the course of the reaction.
