Check Digit Verification of cas no
The CAS Registry Mumber 108281-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,8 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 108281-29:
(8*1)+(7*0)+(6*8)+(5*2)+(4*8)+(3*1)+(2*2)+(1*9)=114
114 % 10 = 4
So 108281-29-4 is a valid CAS Registry Number.

Synthesis and Reactions of α-Ketoaldehyde Adducts of some Heterocyclic Ureas
Hough, T. L.,Hough, I R.,Pannell, R. W.
, p. 1125 - 1130 (2007/10/02)
Pyruvaldehyde reacts with heterocyclic ureas 4a-d giving dihydroxyimidazolidin-2-ones 5a-d.Phenyl glyoxal reacts with 4a giving an analogous adduct 5e.These 1,2-diols are smoothly dehydrated to hydantoins 9a-e which on mild reduction provide monohydroxyim
