127451-58-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127451-58-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,4,5 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127451-58:
(8*1)+(7*2)+(6*7)+(5*4)+(4*5)+(3*1)+(2*5)+(1*8)=125
125 % 10 = 5
So 127451-58-5 is a valid CAS Registry Number.

LOW TEMPERATURE KETENE PREPARATIONS USING NITROSYLTETRACARBONYLCHROMIUM (-II) ANION
Masters, A. P.,Sorensen, T. S.
, p. 5869 - 5872 (2007/10/02)
Methylene and cyclopropyl ketenes can be generated at -100 deg C by the dehalogenation of α-bromoacylhalides using nitrosyltetracarbonylchromium (-II) anion.This facilitates the trapping of these ketenes with more stable ketenes to give mixed ketene dimers.
