122277-66-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122277-66-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,2,7 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 122277-66:
(8*1)+(7*2)+(6*2)+(5*2)+(4*7)+(3*7)+(2*6)+(1*6)=111
111 % 10 = 1
So 122277-66-1 is a valid CAS Registry Number.

Spectroscopy and Dynamics of p-Nitrophenylchlorocarbene

Bonneau, R.,Liu, Michael T. H.

, p. 510 - 512 (1989)

The absolute rate constants for the reaction of p-nitrophenylchlorocarbene with pyridine and tetramethylethylene were found to be respectively 7.5*109 and 2.9*109 l mol-1 s-1.

Formation of Indolizines by the Addition of α-Chloroacrylonitrile to Pyridinium Ylides: Regioselectivity and Hammett Correlation

Bonneau, Roland,Liu, Michael T. H.,Lapouyade, Rene

, p. 1547 - 1548 (2007/10/02)

Cycloaddition of pyridinium ylides to α-chloroacrylonitrile give indolizines: the regioselectivity of the reaction can be rationalized in terms of nucleophilic attack by the ylides on the olefin.
