Check Digit Verification of cas no

The CAS Registry Mumber 1000933-61-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,9,3 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1000933-61:
(9*1)+(8*0)+(7*0)+(6*0)+(5*9)+(4*3)+(3*3)+(2*6)+(1*1)=88
88 % 10 = 8
So 1000933-61-8 is a valid CAS Registry Number.

Diastereoselective Photoredox-Catalyzed [3 + 2] Cycloadditions of N-Sulfonyl Cyclopropylamines with Electron-Deficient Olefins

White, Dawn H.,Noble, Adam,Booker-Milburn, Kevin I.,Aggarwal, Varinder K.

, p. 3038 - 3042 (2021)

A highly diastereoselective, visible-light-induced [3 + 2] cycloaddition between N-sulfonyl cyclopropylamines and electron-deficient olefins is reported. The reactions proceed via the oxidation of a sulfonamide aza-anion by an organic photocatalyst to generate a nitrogen-centered radical. Strain-induced ring opening and intermolecular addition to the olefin generate an intermediate carbon-centered radical that is reduced to an anion prior to 5-exo cyclization. This enables a highly diastereoselective construction of trans-cyclopentanes possessing synthetically useful functional groups.
