Check Digit Verification of cas no

The CAS Registry Mumber 321858-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,8,5 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 321858-90:
(8*3)+(7*2)+(6*1)+(5*8)+(4*5)+(3*8)+(2*9)+(1*0)=146
146 % 10 = 6
So 321858-90-6 is a valid CAS Registry Number.

Recoverable phase-transfer catalysts with fluorinated anions: Generation and reactions of dichlorocarbene and CCl3 anion in the heterogeneous system KOH(s)/CHCl3/nBu4NPF6

Kryshtal, Galina V.,Zhdankina, Galina M.,Zlotin, Sergei G.

, p. 1777 - 1782 (2008)

Tetraalkylammonium salts bearing PF6- and BF 4- anions have been recognized as recoverable phase-transfer catalysts for the synthesis of 1,1-dichlorocyclopropane and α-(trichloromethyl) carbinol derivatives from alkenes or aldehydes in the heterogeneous system KOH(s)/CHCl3. The catalysts retained their catalytic activity over several reaction cycles. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
