Check Digit Verification of cas no

The CAS Registry Mumber 110931-02-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,9,3 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 110931-02:
(8*1)+(7*1)+(6*0)+(5*9)+(4*3)+(3*1)+(2*0)+(1*2)=77
77 % 10 = 7
So 110931-02-7 is a valid CAS Registry Number.

A combined experimental and computational investigation on the unusual molecular mechanism of the lossen rearrangement reaction activated by carcinogenic halogenated quinones

Shan, Guo-Qiang,Yu, Ao,Zhao, Chuan-Fang,Huang, Chun-Hua,Zhu, Ling-Yan,Zhu, Ben-Zhan

, p. 180 - 189 (2015)

The classic Lossen rearrangement is a wellknown reaction describing the transformation of an Oactivated hydroxamic acid into the corresponding isocyanate. In this study, we found that chlorinated benzoquinones (CnBQ) serve as a new class of agents for the activation of benzohydroxamic acid (BHA), leading to Lossen rearrangement. Compared to the classic one, this new kind of CnBQ-activated Lossen rearrangement has the following unique characteristics: (1) The stability of CnBQ-activated BHA intermediates was found to depend not only on the degree but also on the position of Cl-substitution on CnBQs, which can be divided into two subgroups. (2) It is the relative energy of the anionic CnBQ-BHA intermediates that determine the rate of this CnBQ-activated rearrangement, which is the rate-limiting step, and the Cl or H ortho to the reaction site at CnBQ is crucial for the stability of the anionic intermediates. (3) A pKa-activation energy correlation was observed, which can explain why the correlation exists between the rate of the rearrangement and the acidity of the conjugate acid of the anionic leaving group, the hydroxlated quinones. These findings may have broad implications for future research on halogenated quinoid carcinogens and hydroxamate biomedical agents.
