Check Digit Verification of cas no

The CAS Registry Mumber 1243-65-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,4 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1243-65:
(6*1)+(5*2)+(4*4)+(3*3)+(2*6)+(1*5)=58
58 % 10 = 8
So 1243-65-8 is a valid CAS Registry Number.

Diborane Reduction of Penicillins: Preparation of 7-Deoxopenicillanic Acid

Sammes, Peter G.,Smith, Steven,Woolley, Geoffrey T.

, p. 2603 - 2610 (2007/10/02)

The reduction of 6β-acylamidopenicillanates with diborane is shown to proceed by opening of the β-lactam ring to produce the corresponding amino alcohols.The chemistry of the reduction product from benzhydryl 6β-benzyloxycarbonylaminopenicillanate has been explored, in paticular its reaction with methanolic potassium hydroxide; no azetidines are formed.Cyclisation of the amino alcohol prepared from methyl penicillanate may be effected either indirectly, via the corresponding bromide, or directly, by use of a modified Mitsunobu reaction, to produce methyl 7-deoxypenicillanate.
