Check Digit Verification of cas no
The CAS Registry Mumber 131719-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,1 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131719-83:
(8*1)+(7*3)+(6*1)+(5*7)+(4*1)+(3*9)+(2*8)+(1*3)=120
120 % 10 = 0
So 131719-83-0 is a valid CAS Registry Number.

DEGRADATIVE STUDIES ON THE TRICARBONYL CONTAINING MACROLIDE RAPAMYCIN
Goulet, Mark T.,Boger, Joshua
, p. 4845 - 4848 (2007/10/02)
The degradation of rapamycin, a tricarbonyl containing macrolide similar in structure to the potent immunosuppressant FK-506, is described.Three principal fragments are obtained in this process that should have utility in the semi-synthesis of FK-506 and
