475654-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 475654-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,6,5 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 475654-34:
(8*4)+(7*7)+(6*5)+(5*6)+(4*5)+(3*4)+(2*3)+(1*4)=183
183 % 10 = 3
So 475654-34-3 is a valid CAS Registry Number.

Asymmetric dihydroxylation and one-pot epoxidation routes to (+)- and (-)-posticlure: A novel trans-epoxide as a sex pheromone component of Orgyia postica (Walker)
Fernandes, Rodney A,Kumar, Pradeep
, p. 6685 - 6690 (2002)
A highly enantioselective synthesis of (+)- and (-)-posticlure has been achieved. The synthesis features the Sharpless asymmetric dihydroxylation and one-pot epoxidation as the key steps.
