Check Digit Verification of cas no

The CAS Registry Mumber 21086-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,8 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21086-26:
(7*2)+(6*1)+(5*0)+(4*8)+(3*6)+(2*2)+(1*6)=80
80 % 10 = 0
So 21086-26-0 is a valid CAS Registry Number.

Acylation of Alkenes with the Aid of AlCl3 and 2,6-Dibromopyridine

Tanaka, Shinya,Kunisawa, Tsukasa,Yoshii, Yuji,Hattori, Tetsutaro

supporting information, p. 8509 - 8513 (2019/11/03)

Friedel-Crafts-type acylation of alkenes with acyl chlorides has been successfully conducted with a wide substrate scope by the combined use of AlCl3 and 2,6-dibromopyridine. Trisubstituted alkenes afford allylketones or vinylketones depending on the presence or absence of hydrogen atom(s) at the β-position to the acylation site, while monosubstituted alkenes exclusively afford vinylketones.
