Check Digit Verification of cas no

The CAS Registry Mumber 154244-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,2,4 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 154244-57:
(8*1)+(7*5)+(6*4)+(5*2)+(4*4)+(3*4)+(2*5)+(1*7)=122
122 % 10 = 2
So 154244-57-2 is a valid CAS Registry Number.

Thermochemical Study of Complexation of Carbamates with Isocyanates in Solution

Gorbatov,Yablokova,Kheidorov

, p. 1838 - 1839 (2007/10/03)

Complexation of alkyl phenylcarbamates with isocyanates was studied calorimetrically. The compositions, stability constants, and enthalpies of formation of the complexes were determined. The stability of the complexes regularly increases with increasing electron-donor power of substituents in carbamates and electron-acceptor power of isocyanates.
