Check Digit Verification of cas no

The CAS Registry Mumber 1327277-97-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,7,2,7 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1327277-97:
(9*1)+(8*3)+(7*2)+(6*7)+(5*2)+(4*7)+(3*7)+(2*9)+(1*7)=173
173 % 10 = 3
So 1327277-97-3 is a valid CAS Registry Number.

Preparation of α-amino acids by oxidative oxazoline-oxazinone rearrangement-hydrogenation (OOOH). Scope and limitations

Liu, Chaomin,Molinski, Tadeusz F.

, p. 2022 - 2027 (2011/11/29)

The range and scope of the oxidative oxazoline-oxazinone rearrangement-hydrogenation sequence (OOOH)-a short, direct asymmetric synthesis of α-amino acids from carboxylic acids-was explored. The highest yet reported diastereoselectivity for hydrogenation of the oxazinone C=N bond (d.r.=>80:1) is disclosed and rationalized with the aid of ab initio molecular calculations.
