Check Digit Verification of cas no

The CAS Registry Mumber 121328-37-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,3,2 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121328-37:
(8*1)+(7*2)+(6*1)+(5*3)+(4*2)+(3*8)+(2*3)+(1*7)=88
88 % 10 = 8
So 121328-37-8 is a valid CAS Registry Number.

Acyclic Stereoselection in the Alkylation of Chiral Dipole-Stabilized Organolithiums: A Self-Immolative Chirality Transfer Process for the Synthesis of Primary Amines

Gawley, Robert E.,Rein, Kathleen,Chemburkar, Sanjay

, p. 3002 - 3004 (1989)

A comparison of 1,3- and 1,5-asymmetric induction shows the former to have far greater selectivity in the methylation of chiral dipole-stabilized organolithiums.The asymmetric alkylation of N-benzyloxazolidinones is employed as the key step in a new synthesis of primary amines by asymmetric alkylation α to nitrogen.
