Check Digit Verification of cas no

The CAS Registry Mumber 161990-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,9,9 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 161990-12:
(8*1)+(7*6)+(6*1)+(5*9)+(4*9)+(3*0)+(2*1)+(1*2)=141
141 % 10 = 1
So 161990-12-1 is a valid CAS Registry Number.

Chiral Synthesis of L-γ-Carboxylgutamic Acid (L-Gla)

Schuerman, Marla A.,Keverline, Kathryn I.,Hiskey, Richard G.

, p. 825 - 828 (1995)

A two step synthesis involving the use of a chiral template, benzyl (2R,3S)-(-)-6-oxo-2,3-diphenyl-4-morpholine-carboxylate (5a), provides orthogonally protected L-Gla (9) in 60percent overall yield (>99percent ee), with no resolution required.
