Check Digit Verification of cas no

The CAS Registry Mumber 316821-23-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,6,8,2 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 316821-23:
(8*3)+(7*1)+(6*6)+(5*8)+(4*2)+(3*1)+(2*2)+(1*3)=125
125 % 10 = 5
So 316821-23-5 is a valid CAS Registry Number.

A stereoselective synthesis of 1,3,4-substituted β-lactams from polymer-supported chiral oxazolidine aldehyde

Gordon,Bolger,Khan,Balasubramanian

, p. 8621 - 8625 (2000)

The synthesis of a polymer supported chiral oxazolidine aldehyde is described. This intermediate has great potential for the synthesis of biologically interesting compounds. A solid phase stereoselective synthesis of an array of chirally pure β-lactams in high purity is described as a first application of the system. (C) 2000 Elsevier Science Ltd.
