122799-04-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122799-04-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,7,9 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 122799-04:
(8*1)+(7*2)+(6*2)+(5*7)+(4*9)+(3*9)+(2*0)+(1*4)=136
136 % 10 = 6
So 122799-04-6 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
