Check Digit Verification of cas no

The CAS Registry Mumber 1370639-66-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,0,6,3 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1370639-66:
(9*1)+(8*3)+(7*7)+(6*0)+(5*6)+(4*3)+(3*9)+(2*6)+(1*6)=169
169 % 10 = 9
So 1370639-66-9 is a valid CAS Registry Number.

Enantioselective, chromatography-free synthesis of β3-Amino acids with natural and unnatural side chains

Gerfaud, Thibaud,Chiang, Ying-Ling,Kreituss, Imants,Russak, Justin A.,Bode, Jeffrey W.

, p. 687 - 696 (2012/07/13)

β3-Amino acids are key components of some pharmaceuticals, excellent surrogates for metabolically labile α-amino acids, and building blocks for chiral heterocycles. Unfortunately they are not easily accessible in enantiomerically pure form, especially when possessing unnatural side chains. A flexible, chromatography-free process for the synthesis of enantiopure β3-amino acids possessing natural and unnatural side chains is described. The procedure uses inexpensive starting materials and reagents and offers a good alternative to the hazardous and expensive Arndt-Eistert homologation of enantiopure α-amino acids. Its utility has been demonstrated with the preparative scale synthesis of two valuable β3-amino acids possessing unnatural side chains.
