129250-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129250-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,5 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129250-57:
(8*1)+(7*2)+(6*9)+(5*2)+(4*5)+(3*0)+(2*5)+(1*7)=123
123 % 10 = 3
So 129250-57-3 is a valid CAS Registry Number.

Stereoselective cycloadditions of chiral acyl-nitroso compounds; synthetically useful reactions of the adducts
Miller,Procter
, p. 1043 - 1046 (1990)
The adducts from the addition of acyl-nitroso compounds do dienes are shown to undergo reactions which are important for their use in synthesis, via cleavage of the N-O bond to produce monocyclic systems followed by further functionalisation.
