769957-44-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 769957-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,9,9,5 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 769957-44:
(8*7)+(7*6)+(6*9)+(5*9)+(4*5)+(3*7)+(2*4)+(1*4)=250
250 % 10 = 0
So 769957-44-0 is a valid CAS Registry Number.

Total synthesis of (+)-preussin: Control of the stereogenic centers by enantioselective allyltitanations
Canova, Sophie,Bellosta, Véronique,Cossy, Janine
, p. 1811 - 1813 (2007/10/03)
(+)-Preussin was synthesized in ten steps with an overall yield of 6.4% from phenylacetaldehyde. The three stereogenic centers were controlled by enantioselective allyltitanations of aldehydes.
