Check Digit Verification of cas no

The CAS Registry Mumber 64280-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,2,8 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 64280-77:
(7*6)+(6*4)+(5*2)+(4*8)+(3*0)+(2*7)+(1*7)=129
129 % 10 = 9
So 64280-77-9 is a valid CAS Registry Number.

The chemistry of clavulanic acid: Some reactions of esters under neutral, acidic and basic conditions

Brown,Howarth,Ponsford

, p. 2693 - 2696 (2007/10/02)

Investigations into the chemistry of benzyl clavulanate under a variety of reaction conditions has led to acid catalysed one-step conversion to ether and thioether derivatives. Generation of nitrogen-containing displacement products proceeds via the react
