522592-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 522592-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,2,5,9 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 522592-52:
(8*5)+(7*2)+(6*2)+(5*5)+(4*9)+(3*2)+(2*5)+(1*2)=145
145 % 10 = 5
So 522592-52-5 is a valid CAS Registry Number.

Enantioselective synthesis of chromenes
Hardouin, Christophe,Burgaud, Lise,Valleix, Alain,Doris, Eric
, p. 435 - 437 (2007/10/03)
A concise approach for the synthesis of optically active chromenes is reported. The process described herein involves, as the key steps, a Sharpless-epoxidation, a selective deoxygenation, and a ring-closing metathesis.
