Check Digit Verification of cas no

The CAS Registry Mumber 203790-61-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,9 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 203790-61:
(8*2)+(7*0)+(6*3)+(5*7)+(4*9)+(3*0)+(2*6)+(1*1)=118
118 % 10 = 8
So 203790-61-8 is a valid CAS Registry Number.

scheme or table, p. 251 - 259 (2012/05/20)

A practical synthesis of 4-acetoxy-2-azetidinone useful for the preparation of carbapenem- and penem-type antibiotics is described. The synthesis has advantages such as avoiding the tedious and costly column chromatographic or recrystallized separation steps for diastereomers. The overall yield of the product is greatly improved and the process is also more economical for large-scale production. In addition, the mechanism for oxidative decarboxylation is also present.
