647027-76-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 647027-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,7,0,2 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 647027-76:
(8*6)+(7*4)+(6*7)+(5*0)+(4*2)+(3*7)+(2*7)+(1*6)=167
167 % 10 = 7
So 647027-76-7 is a valid CAS Registry Number.

Copper(I)-catalyzed intramolecular addition of N-chloroamides to double bonds; an efficient synthesis of lactams from unsaturated amides
Schulte-Wuelwer, Iris Anne,Helaja, Juho,Goettlich, Richard
, p. 1886 - 1890 (2003)
Copper(I) salts catalyse the intramolecular addition of N-chloramides to carbon-carbon double bonds leading to lactams in almost quantitative yield.
