Check Digit Verification of cas no

The CAS Registry Mumber 1253966-26-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,9,6 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1253966-26:
(9*1)+(8*2)+(7*5)+(6*3)+(5*9)+(4*6)+(3*6)+(2*2)+(1*6)=175
175 % 10 = 5
So 1253966-26-5 is a valid CAS Registry Number.

Cycloaddition of: N -sulfonyl and N -sulfamoyl azides with alkynes in aqueous media for the selective synthesis of 1,2,3-triazoles

Chakraborti, Gargi,Dash, Jyotirmayee,Mandal, Tirtha,Prasanth, Thumpati,Ravichandiran, Velayutham

supporting information, p. 911 - 915 (2022/02/02)

The cycloaddition of N-sulfonyl and N-sulfamoyl azides with terminal alkynes generally produces amide derivatives via ketenimine intermediates. We herein delineate a Cu(i) catalyzed method using a prolinamide ligand that selectively generates N-sulfonyl a

Ring expansion and rearrangements of rhodium(II) azavinyl carbenes

Selander, Nicklas,Worrell, Brady T.,Fokin, Valery V.

supporting information, p. 13054 - 13057 (2013/03/14)

The ring expansion and rearrangement of diazo compounds, specifically rhodium carbenes (derived from the corresponding diazo species), is an efficient and operationally simple method for the construction of structurally unique frameworks.[ 1] Products der
