Check Digit Verification of cas no

The CAS Registry Mumber 2749-35-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,4 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2749-35:
(6*2)+(5*7)+(4*4)+(3*9)+(2*3)+(1*5)=101
101 % 10 = 1
So 2749-35-1 is a valid CAS Registry Number.

Hydroxyl directed: C -arylation: Synthesis of 3-hydroxyflavones and 2-phenyl-3-hydroxy pyran-4-ones under transition-metal free conditions

Paul, Sayantan,Bhattacharya, Asish K.

, p. 444 - 451 (2018/02/06)

An efficient, transition-metal free and direct C-arylation of 3-hydroxychromone moieties in the presence of a base, air as an oxidant and arylhydrazines as arylating agents to furnish highly biologically active flavonols or 3-hydroxyflavones has been developed. We have further extended our methodology for the C-arylation of the 5-hydroxy pyran-4-one moiety. The role of the free hydroxyl group towards C-arylation has been delineated.
