Check Digit Verification of cas no

The CAS Registry Mumber 143868-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,6 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143868-31:
(8*1)+(7*4)+(6*3)+(5*8)+(4*6)+(3*8)+(2*3)+(1*1)=149
149 % 10 = 9
So 143868-31-9 is a valid CAS Registry Number.

Asymmetric synthesis of diastereomerically and enantiomerically pure α-amino-γ-nitro carboxylic esters via Michael addition of the titanated bislactim ether of cyclo (-L-Val-Gly-) to nitroolefines

Busch, Karla,Groth, Ulrich M.,Kuehnle, Wulf,Schoellkopf, Ulrich

, p. 5607 - 5618 (2007/10/02)

The titanated bislactim ethers of cyclo(-L-Val-Gly-) 3 and 7 were added highly diastereoselectively in a 1,4-fashion to the nitro olefines 4 yielding the nitro compounds 5. Upon acidic hydrolysis these nitro compounds 5 afforded the α-amino-γ-nitro acid e
