Check Digit Verification of cas no

The CAS Registry Mumber 67101-90-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,0 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67101-90:
(7*6)+(6*7)+(5*1)+(4*0)+(3*1)+(2*9)+(1*0)=110
110 % 10 = 0
So 67101-90-0 is a valid CAS Registry Number.

Visible-light-induced regioselective cross-dehydrogenative coupling of 2 H-indazoles with ethers

Singsardar, Mukta,Laru, Sudip,Mondal, Susmita,Hajra, Alakananda

, p. 4543 - 4550 (2019)

A visible-light-promoted regioselective C(sp2)-H/C(sp3)-H cross-dehydrogenative coupling between 2H-indazoles and ethers has been achieved using a catalytic amount of rose bengal as an organophotoredox-catalyst and tert-butyl hydroperoxide (TBHP) as an oxidant at ambient temperature under aerobic conditions. A variety of C-3 oxyalkylated 2H-indazoles have been synthesized in moderate to good yields. Mechanistic studies suggest a radical pathway of the present reaction.
