Check Digit Verification of cas no

The CAS Registry Mumber 644990-95-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,4,9,9 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 644990-95:
(8*6)+(7*4)+(6*4)+(5*9)+(4*9)+(3*0)+(2*9)+(1*5)=204
204 % 10 = 4
So 644990-95-4 is a valid CAS Registry Number.

Pyrimidinyl nitronyl nitroxides

Brough, Peter,Pecaut, Jacques,Rassat, Andre,Rey, Paul

, p. 5134 - 5141 (2008/03/13)

The chemistry of 2,2,4,4-substituted pentane derivatives has been investigated with the aim of providing a flexible and versatile synthetic route to pyrimidinyl nitronyl nitroxides, in which the bis-N-oxy fragment is incorporated in a six-membered ring. T

A versatile synthesis of new pyrimidinyl nitronyl nitroxides

Brough,Chiarelli,Pecaut,Rassat,Rey

, p. 2722 - 2723 (2007/10/03)

Pyrimidinyl nitronyl nitroxides where the bis-N-oxy fragment is included in a six-membered ring were prepared from diacetonamine by a sequence of reactions including a Grignard reaction, a Ritter reaction and oxidation of the intermediate pyrimidine; the
