887140-25-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 887140-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,1,4 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 887140-25:
(8*8)+(7*8)+(6*7)+(5*1)+(4*4)+(3*0)+(2*2)+(1*5)=192
192 % 10 = 2
So 887140-25-2 is a valid CAS Registry Number.

A novel heterobifunctional linker for facile access to bioconjugates
Singh, Yashveer,Spinelli, Nicolas,Defrancq, Eric,Dumy, Pascal
, p. 1413 - 1419 (2006)
A convenient synthesis of a novel heterobifunctional linker molecule is described. The linker contains a thiol-reactive nitropyridyl disulfide group (Npys) and an aldehyde-reactive aminooxy group with a propensity to form disulfide and oxime linkages. The
