Check Digit Verification of cas no

The CAS Registry Mumber 67501-72-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,5,0 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67501-72:
(7*6)+(6*7)+(5*5)+(4*0)+(3*1)+(2*7)+(1*2)=128
128 % 10 = 8
So 67501-72-8 is a valid CAS Registry Number.

Olivanic Acid Analogues. Part 1. Total Synthesis of the 7-Oxo-1-azabicyclohept-2-ene-2-carboxylate System and Some Related β-Lactams

Bateson, John H.,Baxter, Andrew J. G.,Roberts, Patricia M.,Smale, Terence C.,Southgate, Robert

, p. 3242 - 3249 (2007/10/02)

4-Allylazetidin-2-one, prepared from penta-1,4-diene and chlorosulphonyl isocyanate, has been used to synthesise the parent 7-oxo-1-azabicyclohept-2-ene-2-carboxylate system of the naturally occurring olivanic acids, using an intramolecular Wittig reaction to construct the 2,3-double bond.Cyclisation of ketones derived from the 4-allyl grouping produced 3-substituted derivatives, while use of the azetidin-2-one prepared from hexa-1,5-diene and chlorosulphonyl isocyanate has given the homologous 8-oxo-1-azabicyclooct-2-ene system.
