52212-92-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52212-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,1 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 52212-92:
(7*5)+(6*2)+(5*2)+(4*1)+(3*2)+(2*9)+(1*2)=87
87 % 10 = 7
So 52212-92-7 is a valid CAS Registry Number.

Cytochalasan Synthesis: Total Synthesis of the Naturally Occuring Cytochalasan Proxiphomin
Thomas, Eric J.,Whitehead, John W. F.
, p. 499 - 505 (2007/10/02)
Proxiphomin (1), a naturally occuring cytochalasan, has been synthesized by a route which uses an intramolecular Diels-Alder reaction of the long chain 3-(1-oxotrienyl)pyrrol-2(5H)-one (18) to form the 13-membered ring.This cyclization gave a mixture
