Check Digit Verification of cas no

The CAS Registry Mumber 1234780-57-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,7,8 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1234780-57:
(9*1)+(8*2)+(7*3)+(6*4)+(5*7)+(4*8)+(3*0)+(2*5)+(1*7)=154
154 % 10 = 4
So 1234780-57-4 is a valid CAS Registry Number.

Synthesis of (+)- and (-)-gossonorol and cyclisation to boivinianin B

Abecassis, Keren,Gibson, Susan E.

experimental part, p. 2938 - 2944 (2010/08/07)

The first enantioselective synthesis of gossonorol has been achieved in good overall yield and excellent enantioselectivity, demonstrating the utility of a novel approach to enantiopure tertiary benzylic alcohols. Epoxidation of enantiopure gossonorol followed by acid-catalysed cyclisation gave a diastereoisomeric mixture of boivinianin B, typical of the diastereoisomeric mixtures of this compound found in nature. Separation of the diastereoisomers and determination of their enantiopurity revealed that the stereochemical integrity of the benzylic alcohol of gossonorol had been preserved during the epoxidation/cyclisation reaction.
