Check Digit Verification of cas no

The CAS Registry Mumber 469874-36-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,9,8,7 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 469874-36:
(8*4)+(7*6)+(6*9)+(5*8)+(4*7)+(3*4)+(2*3)+(1*6)=220
220 % 10 = 0
So 469874-36-0 is a valid CAS Registry Number.

Silica gel-immobilised chiral 1,2-benzenedisulfonimide: a Br?nsted acid heterogeneous catalyst for enantioselective multicomponent Passerini reaction

Antenucci, Achille,Dughera, Stefano,Marra, Francesco

, p. 26083 - 26092 (2021)

A chiral heterogeneous catalyst derivative of (?)-4,5-dimethyl-3,6-bis(1-naphthyl)-1,2-benzenedisulfonimide is proven here to be efficient in a three-component asymmetric Passerini protocol, carried out in a deep eutectic solvent. Reaction conditions are mild and green, while enantioselectivity is excellent. The catalyst was easily recovered and reused with no decrease in its catalytic activity.
