56474-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56474-50-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,4,7 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56474-50:
(7*5)+(6*6)+(5*4)+(4*7)+(3*4)+(2*5)+(1*0)=141
141 % 10 = 1
So 56474-50-1 is a valid CAS Registry Number.

SUBSTITUTION MECHANISMS AT METAL CARBONYL CENTERS; CONVERSION OF Ph3P(CO)4ReBr TO Ph3P(CO)4ReCH3 VIA AN ANIONIC ACYL INTERMEDIATE
Parker, David W.,Marsi, Marianne,Gladysz, J. A.
, p. C1 - C4 (2007/10/02)
The substitution reaction Ph3P(CO)4ReBr + CH3Li = Ph3P(CO)4ReCH3 is shown to occur by initial CH3Li attack upon coordinated CO.
