200948-89-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 200948-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,9,4 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 200948-89:
(8*2)+(7*0)+(6*0)+(5*9)+(4*4)+(3*8)+(2*8)+(1*9)=126
126 % 10 = 6
So 200948-89-6 is a valid CAS Registry Number.

Circular Dichroism Spectra and Molecular Geometry of Six-Membered Ring Anhydrides and Imides
Polonski, Tadeusz
, p. 639 - 648 (2007/10/02)
Several six-membered ring anhydrides and imides of known absolute configuration have been synthesized and their c.d. spectra measured.It has been established that the shape of the c.d. curves of anhydrides is generally similar to those of the correspondin
