Check Digit Verification of cas no

The CAS Registry Mumber 1256782-32-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,7,8 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1256782-32:
(9*1)+(8*2)+(7*5)+(6*6)+(5*7)+(4*8)+(3*2)+(2*3)+(1*2)=177

Cobalt-catalyzed electrophilic amination of arylzincs with N-chloroamines

Qian, Xin,Yu, Zailu,Auffrant, Audrey,Gosmini, Corinne

, p. 6225 - 6229 (2013)

Roles reversed: An efficient cobalt-catalyzed electrophilic amination of arylzinc reagents has been achieved. A variety of functionalized arylzincs and N-chloroamines were coupled under mild conditions (see scheme). Both secondary and tertiary arylamines were obtained in moderate to excellent yields.
