Check Digit Verification of cas no

The CAS Registry Mumber 1114455-20-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,4,4,5 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1114455-20:
(9*1)+(8*1)+(7*1)+(6*4)+(5*4)+(4*5)+(3*5)+(2*2)+(1*0)=107
107 % 10 = 7
So 1114455-20-7 is a valid CAS Registry Number.

Phosphine-catalyzed stereoselective dimerizations of ketenes

Ibrahim, Ahmad A.,Wei, Pei-Hsun,Harzmann, Gero D.,Nalla, Divya,Mondal, Mukulesh,Wheeler, Kraig A.,Kerrigan, Nessan J.

, (2020/12/21)

Full details of optimisation studies of the phosphine-catalyzed ketene homodimerization reaction and the detailed development of an asymmetric variant are discussed. Studies towards the development of a phosphine-catalyzed ketene heterodimerization reaction are revealed. A discussion of possible reaction mechanisms for the dimerization reactions, supported by spectroscopic analysis of intermediates and trapping experiments, is also presented.
