Check Digit Verification of cas no

The CAS Registry Mumber 1610422-31-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,0,4,2 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1610422-31:
(9*1)+(8*6)+(7*1)+(6*0)+(5*4)+(4*2)+(3*2)+(2*3)+(1*1)=105
105 % 10 = 5
So 1610422-31-5 is a valid CAS Registry Number.

Rh(III)-catalyzed cascade oxidative olefination/cyclization of picolinamides and alkenes via C-H activation

Cai, Shangjun,Chen, Chao,Shao, Peng,Xi, Chanjuan

, p. 3142 - 3145 (2014/06/23)

Rh(III)-catalyzed cascade oxidative alkenylation/cyclization of picolinamides and alkenes to furnish pyrido pyrrolone derivatives is described, in which three C-H bonds and one N-H bond broke, while one C-C bond and one C-N bond formed. The reaction proceeded with high yield and high regioselectivity and stereoselectivity. Moreover, copper acetate can also be used in catalytic amounts with O2 serving as the terminal oxidant.
