Check Digit Verification of cas no

The CAS Registry Mumber 24761-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,7,6 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24761-89:
(7*2)+(6*4)+(5*7)+(4*6)+(3*1)+(2*8)+(1*9)=125
125 % 10 = 5
So 24761-89-5 is a valid CAS Registry Number.

INVESTIGATION OF THE STAUDINGER REACTION BETWEEN BICYCLIC PHOSPHITE AND DIAZO COMPOUNDS

Pei, Chengxin,Xu, Xuanlong

, p. 143 - 148 (2007/10/02)

Nine bicyclic phosphatazines were synthesized by the Staudinger reaction between bicyclic phosphite (1) and diazo compounds (2-5), the Elemental Analysis data, IR, 31P NMR and Mass Spectral data of these compounds are reported.The reaction of diazoacetate with bicyclic phosphite was followed by 31P NMR, the concentration-time curve was simulated by Optimal Approximation with a computer.It was found that this reaction consisted of two steps, the first step was second-order and the second was first-order.A possible mechanism is also proposed.Key words: Staudingerreaction; bicyclic phosphite; phosphatazine; optimal approximation; NMR; IR.
