Check Digit Verification of cas no

The CAS Registry Mumber 1265431-53-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,5,4,3 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1265431-53:
(9*1)+(8*2)+(7*6)+(6*5)+(5*4)+(4*3)+(3*1)+(2*5)+(1*3)=145
145 % 10 = 5
So 1265431-53-5 is a valid CAS Registry Number.

A Broad Substrate Scope of Aza-Friedel-Crafts Alkylation for the Synthesis of Quaternary α-Amino Esters

Zhao, Guangkuan,Samanta, Shyam S.,Michieletto, Jessica,Roche, Stéphane P.

supporting information, p. 5822 - 5827 (2020/07/30)

A versatile synthetic protocol of aza-Friedel-Crafts alkylation has been developed for the synthesis of quaternary α-amino esters. This operationally simple alkylation proceeds under ambient conditions with high efficiency, regioselectivity, and an exceptionally broad scope of arene nucleophiles. A key feature of this alkylation is the role associated with the silver(I) salt counteranions liberated during the reaction. Taking advantage of a phase-transfer counteranion/Br?nsted acid pair mechanism, we also report a catalytic enantioselective example of the reaction.
