Check Digit Verification of cas no

The CAS Registry Mumber 100126-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,2 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 100126-79:
(8*1)+(7*0)+(6*0)+(5*1)+(4*2)+(3*6)+(2*7)+(1*9)=62
62 % 10 = 2
So 100126-79-2 is a valid CAS Registry Number.

Lewis acid promoted construction of chromen-4-one and isoflavone scaffolds via regio- and chemoselective domino Friedel-Crafts acylation/Allan-Robinson reaction

Chanda, Tanmoy,Chowdhury, Sushobhan,Koley, Suvajit,Anand, Namrata,Singh, Maya Shankar

supporting information, p. 9216 - 9222 (2014/12/11)

A facile and efficient synthesis of chromen-4-one and isoflavone frameworks is achieved by the domino C-acylation/O-acylation/aldolization sequence. This operationally simple one-pot elegant strategy provides structurally unique chromen-4-ones and isoflavones directly from phenols via concomitant formation of multiple C-C and C-O bonds in a single operation. The outcomes of the buttressing effect, substituent dependence, and catalyst and solvent specificity during the course of the Friedel-Crafts acylation reactions are demonstrated and supported by fitting experiments.
