Check Digit Verification of cas no

The CAS Registry Mumber 1611494-88-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,1,4,9 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1611494-88:
(9*1)+(8*6)+(7*1)+(6*1)+(5*4)+(4*9)+(3*4)+(2*8)+(1*8)=162
162 % 10 = 2
So 1611494-88-2 is a valid CAS Registry Number.

Asymmetric organocatalytic direct C(sp2)-H/C(sp3)-H oxidative cross-coupling by chiral iodine reagents

Wu, Hua,He, Yu-Ping,Xu, Lue,Zhang, Dong-Yang,Gong, Liu-Zhu

supporting information, p. 3466 - 3469 (2014/04/03)

An asymmetric organocatalytic direct C-H/C-H oxidative coupling reaction of N1,N3-diphenylmalonamides has been well established by using chiral organoiodine compounds as catalysts, wherein four C-H bonds were stereoselectively functionalized to give structurally diverse spirooxindoles with high levels of enantioselectivity. More importantly, the findings indicated that chiral hypervalent organoiodine reagents can serve as alternative catalysts for the creation of enantioselective functionalization of inactive C-H bonds. 'I' on the ball: The title oxidative coupling reaction of N 1,N3-diphenylmalonamides has been established by using chiral organoiodine compounds as catalysts. Four C-H bonds were stereoselectively functionalized to give spirooxindoles with high levels of enantioselectivity.
