Check Digit Verification of cas no

The CAS Registry Mumber 33214-38-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,1 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 33214-38:
(7*3)+(6*3)+(5*2)+(4*1)+(3*4)+(2*3)+(1*8)=79
79 % 10 = 9
So 33214-38-9 is a valid CAS Registry Number.

The acid-catalyzed cyclialkylation of 2,4-dimethyl-4-phenylpentan-2-ol led exclusively to the expected product, 2,3-dihydro-1,1,3,3-tetramethyl-1H-indene. However, analogous cyclialkylation of 4-(2-chlorophenyl)-2,4-dimethylpentan-2-ol (1) gave a ca. 1:1
