Check Digit Verification of cas no

The CAS Registry Mumber 993-70-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 993-70:
(5*9)+(4*9)+(3*3)+(2*7)+(1*0)=104
104 % 10 = 4
So 993-70-4 is a valid CAS Registry Number.

Photolysis of Butane-2,3-dione in Fluorocarbon Solvents; a Chemically Induced Nuclear Polarization (CIDNP) Study

Broomhead, Eleanor J.,McLauchlan, Keith A.,Roe, Jonathan C.

, p. 796 - 804 (2007/10/02)

CIDNP observations of the polarized signals from products of radical reactions in solutions of neat butane-2,3-dione in perfluorocyclohexane and perfluorodecalin, and in solutions with added radical scavenger or hydrogen donor, are consistent with three primary processes.There are symmetric (probably) and unsymmetric fragmentation and hydrogen-abstraction by triplet butane-2,3-dione from the starting material, and each yields free radicals.In all solutions the mechanisms of ensuing reactions are suggested.In the presence of CCl4 and CCl3Br pair substitution effects dominate the CIDNP behaviour.When high concentrations of propan-2-ol are present evidence is given for reaction of the excited singlet state of the parent molecule.
