Check Digit Verification of cas no

The CAS Registry Mumber 142955-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,5 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142955-01:
(8*1)+(7*4)+(6*2)+(5*9)+(4*5)+(3*5)+(2*0)+(1*1)=129
129 % 10 = 9
So 142955-01-9 is a valid CAS Registry Number.

Stereoselective Radical-Mediated Cyclization of Norephedrine Derived α-Iodoamides: Experiments and TS-Modelling

Gennari, Cesare,Poli, Giovanni,Scolastico, Carlo,Vassallo, Marco

, p. 793 - 796 (2007/10/02)

Radical-mediated cyclization of norephedrine derived α-iodoamides 1 was found to be highly stereoselective (97:3) favouring diastereoisomer 2.Transition state modelling with a force field developed ad hoc, nicely predicts the stereochemical results.
