1569640-33-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1569640-33-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,6,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1569640-33:
(9*1)+(8*5)+(7*6)+(6*9)+(5*6)+(4*4)+(3*0)+(2*3)+(1*3)=200
200 % 10 = 0
So 1569640-33-0 is a valid CAS Registry Number.

Panda, Niranjan,Mothkuri, Raghavender,Pal, Arpan,Paital, Alok R.
supporting information, p. 2809 - 2814 (2014/03/21)
An unprecedented synthesis of α-naphthol derivatives from the reactions of two molecular equivalents of enol esters in the presence of a copper catalyst is described. This protocol is mild and tolerates various functional groups.
