Check Digit Verification of cas no

The CAS Registry Mumber 72564-60-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,5,6 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72564-60:
(7*7)+(6*2)+(5*5)+(4*6)+(3*4)+(2*6)+(1*0)=134
134 % 10 = 4
So 72564-60-4 is a valid CAS Registry Number.

Zirconium tetrachloride catalysed synthesis of symmetric and unsymmetric ethers from secondary benzylic alcohols

Das, Biswanath,Krishnaiah, Maddeboina,Veeranjaneyulu, Boyapati,Srinivas, Yallamalla,Rao, Yerra Koteswara

, p. 717 - 719 (2008/09/20)

Secondary benzylic alcohols are coupled in the presence of zirconium tetrachloride to afford the corresponding symmetrical ethers in good yields. Unsymmetric ethers are obtained with good selectivity by condensation of two different secondary benzylic alcohols under the action of the same catalyst.
