40630-85-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40630-85-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,3 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40630-85:
(7*4)+(6*0)+(5*6)+(4*3)+(3*0)+(2*8)+(1*5)=91
91 % 10 = 1
So 40630-85-1 is a valid CAS Registry Number.

supporting information, p. 13547 - 13550 (2015/01/09)

A highly efficient addition of alkyl α-bromocarboxylates to enamines by visible light-induced photoredox catalysis is reported. Compared with traditional methods, the reaction described here provided an alternative route for the construction of valuable γ-ketoesters in generally good yields.
