Check Digit Verification of cas no
The CAS Registry Mumber 618-64-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 618-64:
(5*6)+(4*1)+(3*8)+(2*6)+(1*4)=74
74 % 10 = 4
So 618-64-4 is a valid CAS Registry Number.

A convenient method of meta-directing nitration of 3-substituted phenol by lanthanide (III) nitrates
Gu, Shangxiang,Jing, Huanwang,Wu, Jigui,Liang, Yongmin
, p. 2793 - 2797 (2007/10/03)
Thirteen compounds of 3-substituted phenols were nitrated by lanthanide(III) nitrates in a solution of ethyl acetate. Whether the substituents were ortho-, para-directing groups or meta-directing groups, only one kind nitrated product, 3-substituted-5-nitropenol, and its intermediate were obtained respectively.
