4220-75-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4220-75-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4220-75:
(6*4)+(5*2)+(4*2)+(3*0)+(2*7)+(1*5)=61
61 % 10 = 1
So 4220-75-1 is a valid CAS Registry Number.

Rhodium Acetate Catalyzes the Addition of Carbenoids α- to Ether Oxygens

Adams, Julian,Poupart, Marc-Andre,Grenier, Louis,Schaller, Chris,Ouimet, Nathalie,Frenette, Richard

, p. 1749 - 1752 (2007/10/02)

Diazo-carbonyl compounds, when catalyzed by rhodium acetate, insert preferentially adjacent to ether oxygens.This phenomenon was exploited to develop a synthesis of 3(2H)-furanones.
