Check Digit Verification of cas no

The CAS Registry Mumber 123613-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,6,1 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123613-41:
(8*1)+(7*2)+(6*3)+(5*6)+(4*1)+(3*3)+(2*4)+(1*1)=92
92 % 10 = 2
So 123613-41-2 is a valid CAS Registry Number.

(METHYL DIFLUOROACETATE)COPPER REAGENT. REMARKABLE SOLVENT EFFECT ON THE 19F-NMR SPECTRUM, STABILITY AND REACTIVITY

Kitagawa, Osamu,Taguchi, Takeo,Kobayashi, Yoshiro

, p. 389 - 392 (2007/10/02)

The 19F-NMR spectrum, thermal stability and reactivity of (methyl difluoroacetate)copper reagent were found to differ remarkably depending on the solvent (DMSO, DMF, or HMPA) used.With allylic bromide or alkynyl halide a crucial solvent effect for the coupling reactions was observed.
