Check Digit Verification of cas no

The CAS Registry Mumber 24437-56-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,4,3 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 24437-56:
(7*2)+(6*4)+(5*4)+(4*3)+(3*7)+(2*5)+(1*6)=107
107 % 10 = 7
So 24437-56-7 is a valid CAS Registry Number.

Photoinduced remote regioselective radical alkynylation of unactivated C-H bonds

Hu, Qu-Ping,Liu, Yong-Ze,Liu, Yu-Tao,Pan, Fei

supporting information, p. 2295 - 2298 (2022/02/25)

A method for the remote regioselective alkynylation of unactivated C(sp3)-H bonds in diverse aliphatic amides by photogenerated amidyl radicals has been developed. The site-selectivity is dominated via a 1,5-hydrogen atom transfer (HAT) process of the amide. Mild reaction conditions and high regioselectivity are demonstrated in this methodology.

Decatungstate as Direct Hydrogen Atom Transfer Photocatalyst for SOMOphilic Alkynylation

Capaldo, Luca,Ravelli, Davide

supporting information, p. 2243 - 2247 (2021/04/05)

A versatile approach for the alkynylation of a variety of aliphatic hydrogen donors, including alkanes, is reported. We used tetrabutylammonium decatungstate as photocatalyst to generate organoradicals from C-H/Si-H bonds via hydrogen atom transfer. The l
