Check Digit Verification of cas no

The CAS Registry Mumber 1040389-85-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,3,8 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1040389-85:
(9*1)+(8*0)+(7*4)+(6*0)+(5*3)+(4*8)+(3*9)+(2*8)+(1*5)=132
132 % 10 = 2
So 1040389-85-2 is a valid CAS Registry Number.

A highly stereoselective synthesis of chiral α-amino-β-lactams via the Kinugasa reaction employing ynamides

Zhang, Xuejun,Hsung, Richard P.,Li, Hongyan,Zhang, Yu,Johnson, Whitney L.,Figueroa, Ruth

supporting information; experimental part, p. 3477 - 3479 (2009/05/27)

(Chemical Equation Presented) A highly stereoselective synthesis of chiral α-amino-β-lactam through an ynamide-Kinugasa reaction is described. In addition, a mechanistic model is illustrated here to rationalize the observed diastereoselectivity, which depends on both the initial [3 + 2] cycloaddition step and the subsequent protonation for which both are highly selective.
