97402-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97402-77-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,4,0 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 97402-77:
(7*9)+(6*7)+(5*4)+(4*0)+(3*2)+(2*7)+(1*7)=152
152 % 10 = 2
So 97402-77-2 is a valid CAS Registry Number.

An investigation of 2,4′-dihydroxy-3,3′-dimethoxy-5′-methylstilbene using X-ray crystallography and NMR spectroscopy
Li, Shiming,Lundquist, Knut,Stomberg, Rolf
, p. 1012 - 1014 (2007/10/03)
The E and Z forms of the title compound, C17H18O4, were examined by 13C NMR and 1H NMR spectroscopy, and the crystal structure of the E form (m.p. 397-398 K) was determined by X-ray crystallography. E
