141446-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141446-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,4,4 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 141446-91:
(8*1)+(7*4)+(6*1)+(5*4)+(4*4)+(3*6)+(2*9)+(1*1)=115
115 % 10 = 5
So 141446-91-5 is a valid CAS Registry Number.

An Efficient Approach toward 2,3-Dimethylene Pyrroles. Preparation and Reactions of Pyrrolo-3-sulfolenes
Chou, Ta-shue,Chang, Ruei-Chih
, p. 549 - 551 (2007/10/02)
A new route has been developed toward the preparation of pyrrolo-3-sulfolenes, which can be used to generate the corresponding 2,3-dimethylene pyrroles, and their cycloaddition and substitution reactions have been successfully performed.
