Check Digit Verification of cas no

The CAS Registry Mumber 1259-38-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1259-38:
(6*1)+(5*2)+(4*5)+(3*9)+(2*3)+(1*8)=77
77 % 10 = 7
So 1259-38-7 is a valid CAS Registry Number.

13C NMR STUDIES OF SOME COMPLEX NATURAL OXYGEN HETEROCYCLICS. STRUCTURE OF MILLETTIN, A NOVEL ISOFLAVONE ISOLATED FROM MILLETTIA AURICULATA

Raju, K. V. Subba,Srimannarayana, G.,Ternai, B.,Stanley, R.,Markham, K. R.

, p. 957 - 962 (1981)

13C NMR spectra for a variety of isoflavones are presented and analysed.The novel isoflavone, Millettin (Xa) is shown to be closely related to Auriculatin (II).While comparison of the 13C NMR spectra did not readily prove the orientation of the fused pyran ring, the use of acetylation shifts showed unambiguously that the fusion in linear, rather than angular.
