Check Digit Verification of cas no

The CAS Registry Mumber 1269771-64-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,7,7 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1269771-64:
(9*1)+(8*2)+(7*6)+(6*9)+(5*7)+(4*7)+(3*1)+(2*6)+(1*4)=203
203 % 10 = 3
So 1269771-64-3 is a valid CAS Registry Number.

Chiral oxazolidinones as electrophiles: Intramolecular cyclization reactions with carbanions and preparation of functionalized lactams

Gibson, Sarah,Jacobs, Hollie K.,Gopalan, Aravamudan S.

scheme or table, p. 887 - 890 (2011/03/18)

The intramolecular cyclizations of oxazolidinones with carbanions adjacent to sulfones, sulfoxides, and phosphonates proceed in high yields to obtain functionalized γ and δ lactams. The chiral oxazolidinone precursors can be readily synthesized from comme
