Check Digit Verification of cas no
The CAS Registry Mumber 129803-13-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,0 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129803-13:
(8*1)+(7*2)+(6*9)+(5*8)+(4*0)+(3*3)+(2*1)+(1*3)=130
130 % 10 = 0
So 129803-13-0 is a valid CAS Registry Number.

DABCO-Mediated Synthesis and Biological Activity of Cyanihydrin Esters
Hoffmann, H. M. R.,Ismail, Z. M.,Hollweg, Reiner,Zein, Abdul R.
, p. 1807 - 1810 (2007/10/02)
Cyanohydrin esters 1-31 have been prepared from α-ketonitriles and aldehydes using DABCO (1,4-diazabicyclooctane) as nucleophilic acylation catalyst.The modofied piperonal 8 was found to inhibit the formation of thromboxane synthetase.
