Check Digit Verification of cas no

The CAS Registry Mumber 41997-49-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,9,9 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 41997-49:
(7*4)+(6*1)+(5*9)+(4*9)+(3*7)+(2*4)+(1*9)=153
153 % 10 = 3
So 41997-49-3 is a valid CAS Registry Number.

Photocatalytic carbanion generation-benzylation of aliphatic aldehydes to secondary alcohols

Donabauer, Karsten,Maity, Mitasree,Berger, Anna Lucia,Huff, Gregory S.,Crespi, Stefano,K?nig, Burkhard

, p. 5162 - 5166 (2019/06/05)

We present a redox-neutral method for the photocatalytic generation of carbanions. Benzylic carboxylates are photooxidized by single electron transfer; immediate CO2 extrusion and reduction of the in situ formed radical yields a carbanion capable of reacting with aliphatic aldehydes as electrophiles giving the Grignard analogous reaction product.
