Check Digit Verification of cas no

The CAS Registry Mumber 161695-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,6,9 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 161695-12:
(8*1)+(7*6)+(6*1)+(5*6)+(4*9)+(3*5)+(2*1)+(1*2)=141
141 % 10 = 1
So 161695-12-1 is a valid CAS Registry Number.

Some transformations of 2-benzylcyclododecanones prepared by alkylation of cyclododecanone with benzyl halides under conditions of phase transfer catalysis

Zakharkin, L. I.,Churilova, I. M.,Pryanishnikov, A. P.

, p. 861 - 863 (2007/10/02)

Cyclododecanone is readily alkylated with benzyl halides (ArCH2X) to give 2-benzylcyclododecanones under conditions of phase transfer catalysis.Under the action of polyphosphoric acid 2-benzylcyclododecanone undergoes cyclization to give 1,2,3,4,5,6,7,8,9
