Check Digit Verification of cas no

The CAS Registry Mumber 13213-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13213-89:
(7*1)+(6*3)+(5*2)+(4*1)+(3*3)+(2*8)+(1*9)=73
73 % 10 = 3
So 13213-89-3 is a valid CAS Registry Number.

Sunlight-Driven Forging of Amide/Ester Bonds from Three Independent Components: An Approach to Carbamates

Zhao, Yating,Huang, Binbin,Yang, Chao,Chen, Qingqing,Xia, Wujiong

, p. 5572 - 5575 (2016/11/17)

A photoredox catalytic route to carbamates enabled by visible irradiation (or simply sunlight) has been developed. This process leads to a novel approach to the construction of heterocyclic rings wherein the amide or ester motifs of carbamates were assembled from three isolated components. Large-scale experiments were realized by employing continuous flow techniques, and reuse of photocatalyst demonstrated the green and sustainable aspects of this method.
