133616-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133616-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,1 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133616-63:
(8*1)+(7*3)+(6*3)+(5*6)+(4*1)+(3*6)+(2*6)+(1*3)=114
114 % 10 = 4
So 133616-63-4 is a valid CAS Registry Number.

Generation and Trapping of Cyclopropenes from 2-Alkoxy-1,1-dichlorocyclopropanes
Mueller, Paul,Pautex, Nicole
, p. 55 - 64 (2007/10/02)
In presence of crown ether, 2-alkoxy-1,1-dichlorocyclopropanes react with t-BuOK/THF preferentially via ring opening to 2-chloroalk-2-en-1-ones and alkynones or to chlorocyclopropenes.The latter may be intercepted with 1,3-diphenylisobenzofuran, but in th
