Check Digit Verification of cas no
The CAS Registry Mumber 497959-30-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,9,5 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 497959-30:
(8*4)+(7*9)+(6*7)+(5*9)+(4*5)+(3*9)+(2*3)+(1*0)=235
235 % 10 = 5
So 497959-30-5 is a valid CAS Registry Number.

Modular access to 1,2-allenyl ketones based on a photoredox-catalysed radical-polar crossover process
Du, Chan,Fang, Jianghua,Fang, Yewen,Lei, Wan,Li, Yan,Liu, Yongjun
, p. 8502 - 8506 (2021/10/20)
Herein, a new protocol dealing with the preparation of 1,2-allenyl ketones has been successfully developedviathe reactions of enynes with radicals enabled by dual photoredox/copper catalysis. Based on the results of a deuteration experiment and the competition reaction between cyclopropanation and allenation, the mechanism based on a photoredox-neutral-catalysed radical-polar crossover process has been proposed. Synthetic applications of allenes have also been demonstrated.
