573700-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 573700-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,3,7,0 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 573700-23:
(8*5)+(7*7)+(6*3)+(5*7)+(4*0)+(3*0)+(2*2)+(1*3)=149
149 % 10 = 9
So 573700-23-9 is a valid CAS Registry Number.

A new efficient protocol for the preparation of chiral bisphosphines of the BICP family
Genov, Daniel G.
, p. 1949 - 1958 (2007/10/03)
A new procedure for the synthesis of chiral BICP ligands is described. The protocol involves the reaction of sodium diarylphosphide-borane complex with chiral 2,2′-bisbenzenesulfonyl-1,1′-dicyclopentane in toluene, followed by HBF4·OMe2-mediate
