Check Digit Verification of cas no

The CAS Registry Mumber 55182-40-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,1,8 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 55182-40:
(7*5)+(6*5)+(5*1)+(4*8)+(3*2)+(2*4)+(1*0)=116
116 % 10 = 6
So 55182-40-6 is a valid CAS Registry Number.

(3+2) Cycloadditions of Thiouronium Ylides: A Room-Temperature, One-Pot Approach to Dihydrothiophenes

Neuhaus, James D.,Angyal, Peter,Oost, Rik,Maulide, Nuno

, p. 2479 - 2485 (2018)

A room-temperature (3+2) cycloaddition sequence for the synthesis of highly substituted dihydrothiophene derivatives has been developed. By utilizing structurally unique thiocarbonyl ylides, the reactivity of these traditionally high-energy intermediates can be modulated, enabling a synthetically useful transformation to proceed under mild conditions.
