Check Digit Verification of cas no

The CAS Registry Mumber 1620220-80-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,2,2 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1620220-80:
(9*1)+(8*6)+(7*2)+(6*0)+(5*2)+(4*2)+(3*0)+(2*8)+(1*0)=105
105 % 10 = 5
So 1620220-80-5 is a valid CAS Registry Number.

Copper-catalyzed arylsulfonylation of N-arylsulfonyl-acrylamides with arylsulfonohydrazides: Synthesis of sulfonated oxindoles

Tian, Qingshan,He, Ping,Kuang, Chunxiang

supporting information, p. 6349 - 6353 (2014/08/18)

A copper-catalyzed arylsulfonylation of N-arylsulfonyl-acrylamides with sulfonylhydrazides through a tandem radical process was developed. This methodology provided an alternative strategy for the synthesis of sulfonated oxindoles by forming C-S, C-N and C-C bonds in a single operation. the Partner Organisations 2014.
