Check Digit Verification of cas no
The CAS Registry Mumber 781657-62-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,1,6,5 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 781657-62:
(8*7)+(7*8)+(6*1)+(5*6)+(4*5)+(3*7)+(2*6)+(1*2)=203
203 % 10 = 3
So 781657-62-3 is a valid CAS Registry Number.

SYNTHESIS OF POLYSULFATED URONIC ACID GLYCOSIDES
-
Page/Page column 17-18, (2008/06/13)
The invention provides a new synthetic method for the synthesis of pure polysulfated glycosides having well-defined chemical structures. These compounds can be synthesized by sterospecific synthesis from glucose and glucose amine, and glucuronic acid and
