262290-94-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 262290-94-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,2,2,9 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 262290-94:
(8*2)+(7*6)+(6*2)+(5*2)+(4*9)+(3*0)+(2*9)+(1*4)=138
138 % 10 = 8
So 262290-94-8 is a valid CAS Registry Number.

Baker's yeast mediated enantioselective synthesis of the bisabolene sesquiterpenes (+)-epijuvabione and (-)-juvabione

Fuganti, Claudio,Serra, Stefano

, p. 97 - 102 (2007/10/03)

Fermenting baker's yeast converts the unsaturated aldehydes 7 and 11 into the saturated alcohols 8 and 12, respectively. The microbial saturation of the double bond proceeds in high chemical yields and the stereoselectivity of the reduction is strongly influenced by the E:Z ratio of the substrate. Enantiopure 8 and 12 are chiral building blocks for the synthesis of bisabolene sesquiterpenes and their usefulness is shown in the preparation of (+)-epijuvabione 1 and (-)-juvabione 3.
