Check Digit Verification of cas no

The CAS Registry Mumber 1312443-45-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,4,4 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1312443-45:
(9*1)+(8*3)+(7*1)+(6*2)+(5*4)+(4*4)+(3*3)+(2*4)+(1*5)=110
110 % 10 = 0
So 1312443-45-0 is a valid CAS Registry Number.

Carbonylation of functionalized diamine diols to cyclic ureas: Application to derivatives of DMP 450

Darko, Ampofo K.,Curran, F. Chris,Copin, Chloé,McElwee-White, Lisa

, p. 3976 - 3983 (2011/06/25)

Synthesis of the cyclic urea core structure of the HIV protease inhibitor DMP 450 has been achieved via W(CO)6/I2-catalyzed carbonylation of diamine intermediates. Carbonylations of related functionalized diamines to derivatives of the DMP 450 core structure were also examined. Selected diamine diol substrates could be converted to the cyclic urea core structure by catalytic carbonylation without protection of the diol functionality.
