102972-08-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102972-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,9,7 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 102972-08:
(8*1)+(7*0)+(6*2)+(5*9)+(4*7)+(3*2)+(2*0)+(1*8)=107
107 % 10 = 7
So 102972-08-7 is a valid CAS Registry Number.

CYCLOADDITION OF NITRONES AND α,β-UNSATURATED SUGAR LACTONES
Panfil, Irma,Chmielewski, Marek
, p. 4713 - 4716 (2007/10/02)
It was found that 1,3-cycloaddition of nitrones 1-3 to α,β-unsaturated sugar carbonyl compounds 4-8 proceeds regiospecifically to give mixtures of stereoisomers.Nitrones 1-3 entered compounds 4-8 in trans-relation to the existing ring substituent.
