Check Digit Verification of cas no

The CAS Registry Mumber 1620145-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,1,4 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1620145-28:
(9*1)+(8*6)+(7*2)+(6*0)+(5*1)+(4*4)+(3*5)+(2*2)+(1*8)=119
119 % 10 = 9
So 1620145-28-9 is a valid CAS Registry Number.

Organocatalytic domino sequence to asymmetrically access spirocyclic oxindole-α-methylene-γ-lactams

Xie, Zhen-Zhen,Qian, Yu-Lun,Zheng, Yu,Zhao, Qing-Lan,Xiao, Jun-An,Xiang, Hao-Yue,Chen, Kai,Yang, Hua

, (2021)

An asymmetric allylic alkylation-lactamization domino sequence of 3-aminooxindoles with Morita-Baylis-Hillman carbonates catalyzed by quinidine derivative (β-ICD) was developed. And a series of chiral spirocyclic oxindole-α-methylene-γ-lactams have been facilely prepared in good yields and stereoselectivities. This developed protocol would broaden the utilization of Morita-Baylis-Hillman carbonates in asymmetric construction of spirocyclic oxindoles.
