Check Digit Verification of cas no

The CAS Registry Mumber 220178-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,1,7 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220178-53:
(8*2)+(7*2)+(6*0)+(5*1)+(4*7)+(3*8)+(2*5)+(1*3)=100
100 % 10 = 0
So 220178-53-0 is a valid CAS Registry Number.

, p. 111 - 115 (1999)

Enantiomerically pure α,α-dichloro β-fluoroalkyl γ-p-tolylthio γ- butyrolactones trans-6a-c have been obtained with excellent stereocontrol (> 98:2) and enantiomeric purity (> 98:2) by sulfoxide-directed lactonization (Marino's annulation reaction) of β-f
