691371-38-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 691371-38-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,3,7 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 691371-38:
(8*6)+(7*9)+(6*1)+(5*3)+(4*7)+(3*1)+(2*3)+(1*8)=177
177 % 10 = 7
So 691371-38-7 is a valid CAS Registry Number.

Synthesis of 7-oxa-phomopsolide e and its C-4 epimer
Li, Miaosheng,Scott, Jana,O'Doherty, George A.
, p. 1005 - 1009 (2007/10/03)
A flexible, enantioselective route to highly functionalized α,β-unsaturated δ-lactones has been applied to the synthesis of 7-oxa-phomopsolide E and its C-4 epimer. This approach relies on the application of the Noyori asymmetric hydrogenation of furyl ke
