Check Digit Verification of cas no

The CAS Registry Mumber 7556-50-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,5 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7556-50:
(6*7)+(5*5)+(4*5)+(3*6)+(2*5)+(1*0)=115
115 % 10 = 5
So 7556-50-5 is a valid CAS Registry Number.

, p. 93 - 94 (2000)

The title compound, C23H28O2, was obtained from the reaction of acetone with meta-cresol. The molecular structure consists of two identical subunits which are nearly perpendicular to each other. The oxygen-containing rings are not planar and the molecule is chiral. The crystal structure consists of chains of molecules of the same chirality arranged along the [010] axis.
