112181-91-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112181-91-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,1,8 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112181-91:
(8*1)+(7*1)+(6*2)+(5*1)+(4*8)+(3*1)+(2*9)+(1*1)=86
86 % 10 = 6
So 112181-91-6 is a valid CAS Registry Number.

A new procedure for the in situ generation of methylene ketenes
Masters, Andrew P.,Sorensen, Ted S.,Tran, Phu Mahn
, p. 1499 - 1502 (2007/10/02)
The reaction of pentacarbonylmanganate anion 3 and 2-bromopropenoyl chlorides 2 leads to 2,4-alkylidenecyclobutane-1,3-diones 5.The latter are formed from dimerization of the corresponding methylene ketenes 1 so that the reaction of 2 and 3 constitutes a
