180573-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 180573-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,5,7 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 180573-22:
(8*1)+(7*8)+(6*0)+(5*5)+(4*7)+(3*3)+(2*2)+(1*2)=132
132 % 10 = 2
So 180573-22-2 is a valid CAS Registry Number.

Radical cyclization of thio- and seleno-esters - An intramolecular acylation approach
Kim, Sunggak,Jon, Sang Yong
, p. 1335 - 1336 (2007/10/03)
Both thio- and seleno-esters are utilized as carbonyl equivalent radical acceptors in radical cyclizations, where selenoesters are more efficient than thioesters due to the better leaving ability of the phenylseleno group.
