1570-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1570-97-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,7 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1570-97:
(6*1)+(5*5)+(4*7)+(3*0)+(2*9)+(1*7)=84
84 % 10 = 4
So 1570-97-4 is a valid CAS Registry Number.

Geometrisch enantiomorphe Cyclobutan-Derivate
Prelog, Vladimir,Thix, Jean,Srikrishnan, Tamarapu
, p. 2622 - 2644 (2007/10/02)
The concept of geometrical enantiomorphism of unsaturated molecules is generalized to cover other planar rectangular arrangements of four ligands of which two are enantiomorphic.Three pairs of geometrically enantiomorphic cyclobutane derivatives were prep
