Check Digit Verification of cas no
The CAS Registry Mumber 917379-11-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,3,7 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 917379-11:
(8*9)+(7*1)+(6*7)+(5*3)+(4*7)+(3*9)+(2*1)+(1*1)=194
194 % 10 = 4
So 917379-11-4 is a valid CAS Registry Number.

Total synthesis of (S)-equol
Heemstra, Jennifer M.,Kerrigan, Sean A.,Doerge, Daniel R.,Helferich, William G.,Boulanger, William A.
, p. 5441 - 5443 (2007/10/03)
The first enantioselective total synthesis of (S)-equol is reported. The described route relies on an Evans alkylation to form the stereocenter and an intramolecular Buchwald etherification to generate the chroman ring. Key features of this method include its brevity, its scalability, and the low cost of starting materials.
