Check Digit Verification of cas no

The CAS Registry Mumber 100187-46-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,8 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 100187-46:
(8*1)+(7*0)+(6*0)+(5*1)+(4*8)+(3*7)+(2*4)+(1*6)=80
80 % 10 = 0
So 100187-46-0 is a valid CAS Registry Number.

Synthesis of 5-, 6-, 7- and 18-mono-13C-labelled retinals

Courtin, J. M. L.,'t Lam, G. K.,Peters, A. J. M.,Lugtenburg, J.

, p. 281 - 288 (2007/10/02)

Four retinals labelled at positions 5,6,7 and 18 with 13C were obtained via simple schemes involving only a few steps with >98percent chemical purity and 92percent 13C incorporation. (5-13C)Retinal was obtained in 26percent yield from K13CN. (6-13C)- and (7-13C)Retinal were obtained in 37percent yield from (2-13C)- and (1-13C)acetonitrile, respectively, while (18-13C)retinal was obtained in 8 steps and 4percent yield starting from 13CH3I.Their 13C - 1H and 13C - i142213C NMR coupling constants were determined.
