23930-02-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23930-02-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,3 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23930-02:
(7*2)+(6*3)+(5*9)+(4*3)+(3*0)+(2*0)+(1*2)=91
91 % 10 = 1
So 23930-02-1 is a valid CAS Registry Number.

THE COUMARIN COMPOSITION OF Seseli tortuosum
Abyshev, A. Z.,Abyshev, D. Z.
, p. 668 - 672 (1983)
The results are given of the identification of the known pyranocoumarin campestrinol (I), and the structures of four new coumarin derivatives have been studied - tortuosin (II), tortuosinin (III), tortuosinol (IV), and tortuosidin (V).On the basis of their spectral characteristics and chemical transformations, the corresponding structures have been established for compounds (II)-(V).
