Check Digit Verification of cas no
The CAS Registry Mumber 57901-39-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,0 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57901-39:
(7*5)+(6*7)+(5*9)+(4*0)+(3*1)+(2*3)+(1*9)=140
140 % 10 = 0
So 57901-39-0 is a valid CAS Registry Number.

, p. 3244 - 3250 (2007/10/02)
Treatment of 14-bromo-6-dehydroxysantoninic acid (1a) with 10percent Na2CO3-acetone solution gave the lactone dimer (2), the spiro dimer (5), and a hydroxy compound (4), in 17percent, 40percent, and 21percent yields, respectively.The molecular structure of the major product, 6-dehydroxysantoninic acid spiro dimer (5), was confirmed by X-ray crystallographic analysis.The mechanism of formation of 5 during the course of this reaction is discussed.Keywords - sesquiterpene; santonin derivatives; NMR; X-ray analysis; HOMO/LUMO reaction mechanism; dimerization
