Check Digit Verification of cas no
The CAS Registry Mumber 179897-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,8,9 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 179897-89:
(8*1)+(7*7)+(6*9)+(5*8)+(4*9)+(3*7)+(2*8)+(1*9)=233
233 % 10 = 3
So 179897-89-3 is a valid CAS Registry Number.

Cascade Process for Direct Transformation of Aldehydes (RCHO) to Nitriles (RCN) Using Inorganic Reagents NH2OH/Na2CO3/SO2F2 in DMSO
Fang, Wan-Yin,Qin, Hua-Li
, p. 5803 - 5812 (2019/05/14)
A simple, mild, and practical process for direct conversion of aldehydes to nitriles was developed feathering a wide substrate scope and great functional group tolerability (52 examples, over 90% yield in most cases) using inorganic reagents (NH2OH/Na2CO3/SO2F2) in DMSO. This method allows for transformations of readily available, inexpensive, and abundant aldehydes to highly valuable nitriles in a pot, atom, and step-economical manner without transition metals. This protocol will serve as a robust tool for the installation of cyano-moieties to complicated molecules.
