Check Digit Verification of cas no

The CAS Registry Mumber 20536-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,3 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20536-45:
(7*2)+(6*0)+(5*5)+(4*3)+(3*6)+(2*4)+(1*5)=82
82 % 10 = 2
So 20536-45-2 is a valid CAS Registry Number.

Alkylmetal Asymmetric Reduction. 18. Starting Materials in the Preparation of New Chiral Reducing Agents: Synthetic Approach to Primary Alkyl Halides Derived from (+)-Camphor

Falorni, Massimo,Lardicci, Luciano,Giacomelli, Giampaolo

, p. 5291 - 5294 (1986)

2,2-Dimethyl-3-(chloromethyl)bicycloheptane (camphanyl chloride), camphanyl bromide, 1,7,7-trimethyl-2-(chloromethyl)bicycloheptane , and 2-(bromomethyl)bornane were prepared from (+)-camphor.All these compounds were obtained as mixture of exo and endo isomers in various ratios depending upon the synthetic path adopted.A loss of diastereomeric purity during the halogenations of corresponding alcohols was observed.
