745058-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 745058-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,5,0,5 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 745058-49:
(8*7)+(7*4)+(6*5)+(5*0)+(4*5)+(3*8)+(2*4)+(1*9)=175
175 % 10 = 5
So 745058-49-5 is a valid CAS Registry Number.

Efficient asymmetric syntheses of (+)-strictifolione
Enders, Dieter,Lenzen, Achim,Müller, Michael
, p. 1486 - 1496 (2007/10/03)
The asymmetric synthesis and a formal asymmetric synthesis of (+)-strictifolione are described. As key step in both approaches the Julia-Kocienski olefination to create an E-configured alkene was used. The anti-1,3-diol moiety was synthesized by employing
