Check Digit Verification of cas no

The CAS Registry Mumber 92207-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,2,0 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 92207-33:
(7*9)+(6*2)+(5*2)+(4*0)+(3*7)+(2*3)+(1*3)=115
115 % 10 = 5
So 92207-33-5 is a valid CAS Registry Number.

Visible-Light-Mediated Rose Bengal-Catalyzed α-Hydroxymethylation of Ketones with Methanol

Yang, Jingya,Xie, Dongtai,Zhou, Hongyan,Chen, Shuwen,Duan, Jiaokui,Huo, Congde,Li, Zheng

supporting information, p. 3471 - 3476 (2018/09/12)

A visible-light-mediated α-hydroxymethylation of ketones using methanol as the hydroxymethylating reagent has been developed. Using 1 mol% rose bengal as the photosensitizer and air as the green oxidant, the reactions proceeded smoothly at room temperature. Experimental studies indicate the reaction proceeded via a radical pathway. (Figure presented.).
