Check Digit Verification of cas no

The CAS Registry Mumber 109916-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,1 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109916-68:
(8*1)+(7*0)+(6*9)+(5*9)+(4*1)+(3*6)+(2*6)+(1*8)=149
149 % 10 = 9
So 109916-68-9 is a valid CAS Registry Number.

Stereochemical Aspects of the Bose Reaction for α-Amino-β-lactam Synthesis

Manhas, Maghar S.,Veen, James M. van der,Wagle, Dilip R.,Hegde, Vinod R.,Bari, Shamsher S.,et al.

, p. 1095 - 1104 (2007/10/02)

Stereochemical aspects of the Bose reaction (formation of α-azido-β-lactams from an activated form of azidoacetic acid and imino compounds in the presence of a base) are examined.Substituted β-lactams prepared by stereocontrolled synthesis (including enantiospecific synthesis) are shown to be useful intermediates for β-lactam antibiotics, sugars, alkaloids and other natural products.A stereospecific synthesis of an optically active 3-aminosugar related to gentosamine starting from a β-lactam synthon is described.
