Check Digit Verification of cas no

The CAS Registry Mumber 1609647-77-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,6,4 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1609647-77:
(9*1)+(8*6)+(7*0)+(6*9)+(5*6)+(4*4)+(3*7)+(2*7)+(1*7)=199
199 % 10 = 9
So 1609647-77-9 is a valid CAS Registry Number.

ABSORBABLE BRANCHED POLYESTERS AND POLYURETHANES

-

, (2014/05/25)

The present invention relates to the discovery of a new class of hydrolysable isocyanates, hydrolysable branched polyols and branched absorbable polyesters and polyurethanes prepared therefrom. The resultant absorbable polymers are useful for drug delivery, stents, highly porous foam, reticulated foam, tissue engineering, tissue adhesives, adhesion prevention, bone wax formulations, medical device coatings, surface modifying agents and other implantable medical devices. In addition, these absorbable polymers can have a controlled hydrolytic degradation profile.
