Check Digit Verification of cas no

The CAS Registry Mumber 116773-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,7,7 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 116773-05:
(8*1)+(7*1)+(6*6)+(5*7)+(4*7)+(3*3)+(2*0)+(1*5)=128
128 % 10 = 8
So 116773-05-8 is a valid CAS Registry Number.

Radical N-heterocyclic carbene catalysis for β-ketocarbonyl synthesis

Ishii, Takuya,Nagao, Kazunori,Ohmiya, Hirohisa

, (2021/06/07)

N-Heterocyclic carbene-catalyzed radical cross-coupling between aldehydes and α-bromoesters or α-bromoamides is described. β-Ketocarbonyl compounds having a quaternary carbon center at the α-position can be synthesized under mild reaction conditions. Both aromatic and aliphatic aldehydes are suitable acyl donors by employing proper NHC catalyst precursors.
