Check Digit Verification of cas no

The CAS Registry Mumber 76347-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,3,4 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76347-07:
(7*7)+(6*6)+(5*3)+(4*4)+(3*7)+(2*0)+(1*7)=144
144 % 10 = 4
So 76347-07-4 is a valid CAS Registry Number.

Reactive Nitrogenous Molecules from Meldrum's Acid Derivatives, Pyrrole-2,3-diones, and Isoxazolones

Briehl, Horst,Lukosch, Adelheid,Wentrup, Curt

, p. 2772 - 2779 (2007/10/02)

Flash vacuum pyrolysis of 5-(aminomethylidene)-2,2-dimethyl-1,3-dioxane-4,6-diones (Meldrum's acid derivatives) 12 gives 4-hydroxyquinolines/4-quinolones 15 or 3-enaminoacroleins 22 in good to excellent yields.Intermediate (aminomethylene)ketenes and imidoylketenes are directly observed and their transformation into product 22 monitored by low-temperature IR spectroscopy.Imidoylketenes are also formed and observed upon thermal CO extrusion from pyrrole-2,3-diones 16.Isocyanoamines and fulminates are generated by pyrolysis of hydrazono- or oximino-Meldrum's acid derivatives 32 and 39, monitored by IR spectroscopy, and found to rearrange to cyanamides and cyanates, depending on substituents.The thermal reactions of isoxazol-5(4H)-ones and Meldrum's acid derivatives are compared and discussed.
