Check Digit Verification of cas no

The CAS Registry Mumber 871876-82-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,8,7 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 871876-82:
(8*8)+(7*7)+(6*1)+(5*8)+(4*7)+(3*6)+(2*8)+(1*2)=223
223 % 10 = 3
So 871876-82-3 is a valid CAS Registry Number.

A practical oxidative conversion of aldehydes into N-chloroaldimines

Jin, Can,Wang, Feng,Sun, Bin,Zhuang, Xiaohui

, p. 547 - 551 (2018/11/27)

A novel method for the preparation of N-chloroaldimines from commonly available aromatic aldehydes has been developed. The reaction proceeded effectively by two steps: aldehydes were initially transformed into imines and then chloro-substitution with NaClO2 gave the N-chloroaldimines. This simple protocol allows for the preparation of a variety of aromatic N-chloroaldimines in moderate to excellent yields without the isolation of the imine intermediate. We also found that 3-nitrobenzaldehyde and 4-cyanobenzaldehyde were converted into the related benzonitrile directly under the standard conditions.
