Check Digit Verification of cas no

The CAS Registry Mumber 100343-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,3,4 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 100343-41:
(8*1)+(7*0)+(6*0)+(5*3)+(4*4)+(3*3)+(2*4)+(1*1)=57
57 % 10 = 7
So 100343-41-7 is a valid CAS Registry Number.

Competitive epoxidation and quinone formation in the dimethyldioxirane oxidation of diazoquinones as ambident nucleophiles

Adam, Waldemar,Hadjiarapoglou, Lazaros,Mielke, Karsten,Treiber, Alexander

, p. 5625 - 5628 (1994)

In addition to the expected dimethyldioxirane (DMD) oxidation of diazoquinones 1 to their quinones 2, the corresponding epoxy quinones 3 are formed directly and not as secondary overoxidation products of the quinones 2 since the latter are persistent towards DMD under these conditions; this novel oxidation is rationalized in terms of the ambident nucleophilic nature of the diazoquinones and corroborated by MO (AMI) calculations.
