126571-59-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126571-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,7 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 126571-59:
(8*1)+(7*2)+(6*6)+(5*5)+(4*7)+(3*1)+(2*5)+(1*9)=133
133 % 10 = 3
So 126571-59-3 is a valid CAS Registry Number.

CYCLOADDITION OF β-SUBSTITUTED ENONES TO A BICYCLICSYDNONE: OBSERVATION OF AN UNEXPECTED FACILE HYDROCARBON ELIMINATION
Larsen, Scott D.,Martinborough, Esther
, p. 4625 - 4628 (2007/10/02)
Cycloaddition of β-alkyl or β-arylenones to bicyclic sydnone 3 in the absence of added oxidant affords mixtures of the tetrahydropyrazolopyridines 4 and 5.The amount of 5 formed was dependent on the nature of R.
