Check Digit Verification of cas no

The CAS Registry Mumber 220587-30-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,5,8 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 220587-30:
(8*2)+(7*2)+(6*0)+(5*5)+(4*8)+(3*7)+(2*3)+(1*0)=114
114 % 10 = 4
So 220587-30-4 is a valid CAS Registry Number.

Novel thiopyrano[3,2-b] and cycloalkeno[1,2-b]indole derivatives with high inhibitory properties in LTB4 production

Kuehm-Caubere, Catherine,Caubere, Paul,Jamart-Gregoire, Brigitte,Pfeiffer, Bruno,Guardiola-Lemaitre, Beatrice,Manechez, Dominique,Renard, Pierre

, p. 51 - 61 (2007/10/03)

Series of thiopyrano[3,2-b] and cycloalkeno[1,2-b]indoles were synthesized and evaluated in order to determine the necessary structural requirements for high leukotrienes biosynthesis inhibition. In vitro experiments showed that compounds 11b and 12b belonging to the second series were the most active and selective compounds on LTB4 production. Further in vivo investigations have shown additional very significant activity in the acute phorbol ester induced mouse ear swelling which is predictive of potential antipsoriatic properties.
