Check Digit Verification of cas no

The CAS Registry Mumber 109954-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,5 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109954-05:
(8*1)+(7*0)+(6*9)+(5*9)+(4*5)+(3*4)+(2*0)+(1*5)=144
144 % 10 = 4
So 109954-05-4 is a valid CAS Registry Number.

INVESTIGATION OF THE MECHANISMS OF FORMATION OF HETEROCYCLES BY NMR SPECTROSCOPY

Selivanov, S. I.,Golodova, K. G.,Ershov, B. A.

, p. 1858 - 1865 (2007/10/02)

The 13C chemical shifts were obtained for the unstable intermediate products in the reactions of 1,3-diketones R1COCH2COR2 (R1, R2= Me, Et, t-Bu, CF3) with hydrazines NH2NHR3 (R3= H, Me, Ph).The results confirm that they have hydroxypyrazoline, hydrazone, dihydroxypyrazoline, and ketohydroxyhydrazine structures.It was shown that 13C NMR spectroscopy can be used for analysis of the complex nonequilibrium reaction mixtures.
