Check Digit Verification of cas no

The CAS Registry Mumber 35459-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,4,5 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 35459-97:
(7*3)+(6*5)+(5*4)+(4*5)+(3*9)+(2*9)+(1*7)=143
143 % 10 = 3
So 35459-97-3 is a valid CAS Registry Number.

Benzoquinones and Related Compounds. Part 2. Preferred Conformations of Some Acyl-1,4-benzoquinones in Solution

Bruce, Malcolm,Heatley, Frank,Ryles, Roderick G.,Scrivens, James H.

, p. 860 - 866 (2007/10/02)

Studies based on polarographic reduction potentials, electronic absorption spectra, and (1)H and (13)C nuclear magnetic relaxation data show that in solution the preferred conformation of formyl-1,4-benzoquinone is that with the formyl and quinonoid groups coplanar, and the formyl carbonyl group anti to the 1-carbonyl, whereas that of acetyl- and pivaloyl-1,4-benzoquinone has the acyl groups approximately perpendicular to the quinonoid ring.
