Check Digit Verification of cas no

The CAS Registry Mumber 34441-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,4,4 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34441-01:
(7*3)+(6*4)+(5*4)+(4*4)+(3*1)+(2*0)+(1*1)=85
85 % 10 = 5
So 34441-01-5 is a valid CAS Registry Number.

Access to Cyanoimines Enabled by Dual Photoredox/Copper-Catalyzed Cyanation of O-Acyl Oximes

Wei, Ziyan,Yu, Shouyun,Zhang, Ai Hua,Zhang, Hao

, p. 7315 - 7320 (2020/10/02)

An efficient strategy for the synthesis of pharmaceutically important and synthetically useful cyanoimines, as well as cyanamides, has been described. This strategy is enabled by dual photoredox/copper-catalyzed cyanation of O-acyl oximes or O-acyl hydroxamides. This state of the art protocol for cyanoimines and cyanamides features readily available starting materials, mild reaction conditions, good functional group tolerance, and operational simplicity. The resultant cyanoimines can be transformed into structurally diverse and functionally important N-containing heterocycles.
