Check Digit Verification of cas no

The CAS Registry Mumber 208402-14-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,4,0 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 208402-14:
(8*2)+(7*0)+(6*8)+(5*4)+(4*0)+(3*2)+(2*1)+(1*4)=96
96 % 10 = 6
So 208402-14-6 is a valid CAS Registry Number.

Two new improved approaches to the synthesis of coumarin-based prodrugs

Zheng, Ailian,Wang, Wei,Zhang, Huijuan,Wang, Binghe

, p. 4237 - 4254 (2007/10/03)

Our laboratory has recently reported the development of a coumarin- based, esterase-sensitive prodrug system for the preparation of prodrugs of amines, peptides, and peptidomimetics. Biological evaluations including animal studies have demonstrated the cl

Chemical feasibility studies of a potential coumarin-based prodrug system

Wang, Binghe,Zhang, Huijuan,Wang, Wei

, p. 945 - 950 (2007/10/03)

By using model amines, several amides of coumarinic acid with the phenolic hydroxyl group protected as an ester were prepared. These model amides underwent a facile (t( 1/2 ) 1.5-31 min) lactonization to release the original amine compounds upon esterase catalyzed hydrolysis of the phenolic ester. Such a system can be used for the preparation of esterase-sensitive prodrugs of amine-containing compounds or peptids.
