Check Digit Verification of cas no

The CAS Registry Mumber 203312-82-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,3,1 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 203312-82:
(8*2)+(7*0)+(6*3)+(5*3)+(4*1)+(3*2)+(2*8)+(1*2)=77
77 % 10 = 7
So 203312-82-7 is a valid CAS Registry Number.

Diastereocontrolled synthesis of pyrrolidines by nickel promoted tandem cyclization-quenching of aminobromodienes

Cancho, Yolanda,Martin, Joan M.,Martinez, Maria,Llebaria, Amadeu,Moreto, Josep M.,Delgado, Antonio

, p. 1221 - 1232 (2007/10/03)

The nickel promoted tandem cyclization-quenching of tethered aminobromodienes has been extended to the synthesis of 2,3,4-trisubstituted pyrrolidines. By a judicious choice of substituents on the starting aminohalodiene, the diastereoselectivity of the process can be efficiently controlled. When a chiral auxiliary on the nitrogen atom is used, enantiomerically enriched pyrrolidines can be obtained after removal of the auxiliary.
