Check Digit Verification of cas no
The CAS Registry Mumber 1221000-83-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,0,0 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1221000-83:
(9*1)+(8*2)+(7*2)+(6*1)+(5*0)+(4*0)+(3*0)+(2*8)+(1*3)=64
64 % 10 = 4
So 1221000-83-4 is a valid CAS Registry Number.

Multicomponent asymmetric reactions mediated by proline lithium salt
Renzi, Polyssena,Overgaard, Jacob,Bella, Marco
, p. 980 - 983 (2010)
The multicomponent reaction between proline lithium salt, 2-cyclohexen-1-one and aliphatic aldehydes affords the 4-alkylidene-2- cyclohexen-1-ones, which are interesting fragrances, and bicyclic amino acids that bear four additional stereocenters, obtaine
