Check Digit Verification of cas no

The CAS Registry Mumber 22937-92-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,3 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22937-92:
(7*2)+(6*2)+(5*9)+(4*3)+(3*7)+(2*9)+(1*2)=124
124 % 10 = 4
So 22937-92-4 is a valid CAS Registry Number.

A simple and straightforward synthesis of phenyl isothiocyanates, symmetrical and unsymmetrical thioureas under ball milling

Zhang, Ze,Wu, Hao-Hao,Tan, Ya-Jun

, p. 16940 - 16944 (2013)

Promoted by KOH under ball milling, anilines were efficiently transformed into isothiocyanates (in presence of 5.0 equiv. CS2) or symmetrical thioureas (in presence of 1.0 equiv. CS2), without using any other harsh or toxic decomposition reagent. Some in situ generated isothiocyanates can directly "click" with other amines to afford unsymmetrical thioureas.
