Check Digit Verification of cas no

The CAS Registry Mumber 1052676-87-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,2,6,7 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1052676-87:
(9*1)+(8*0)+(7*5)+(6*2)+(5*6)+(4*7)+(3*6)+(2*8)+(1*7)=155
155 % 10 = 5
So 1052676-87-5 is a valid CAS Registry Number.

Diastereoselective synthesis of carbapenams via Kinugasa reaction

Stecko, Sebastian,Mames, Adam,Furman, Bartlomiej,Chmielewski, Marek

supporting information; experimental part, p. 7402 - 7404 (2009/05/07)

(Chemical Equation Presented) A facile approach to carbapenams via Kinugasa reaction between terminal copper acetylides and nonracemic cyclic nitrones derived from malic and tartaric acid is reported. The stereochemical preferences observed in these reactions are explained. The reaction provides an entry to the carbapenams basic skeleton.
