Check Digit Verification of cas no

The CAS Registry Mumber 87184-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,1,8 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87184-65:
(7*8)+(6*7)+(5*1)+(4*8)+(3*4)+(2*6)+(1*5)=164
164 % 10 = 4
So 87184-65-4 is a valid CAS Registry Number.

, p. 11174 - 11184 (2014/01/06)

An efficient and rapid procedure for ring opening reaction of various epoxides with phenol and thiophenol derivatives was developed. The procedure can be obtained at room temperature under solvent-free condition in presence of (C4H12N2)2[BiCl6] Cl·H2O (1 mol %). This catalyst can be reused several times without significant loss of activity.
