Check Digit Verification of cas no

The CAS Registry Mumber 87749-19-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,4 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87749-19:
(7*8)+(6*7)+(5*7)+(4*4)+(3*9)+(2*1)+(1*9)=187
187 % 10 = 7
So 87749-19-7 is a valid CAS Registry Number.

Samaraweera, Upasiri,Sotheeswaran, Subramaniam,Sultanbawa, M. Uvais S.,Balasubramaniam, Sinnathamby

, p. 703 - 706 (2007/10/02)

Calophyllum bracteatum, C. calaba (var. calaba), C. moonii (=C. soulattri), C. thwaitesii, C. trapezifolium, C. walkeri, and C. zeylanicum (=C. lankaensis) have been examined for their bark acids.A new acid, calozeylanic acid,has been isolated from three species and has been identified as (2R,3R)-2,3-dimethyl-5-hydroxy-6-(3-methylbuthyl)-6-(3,7-dimethylocta-3,6-dienyl)-8-(2-carboxy-1-phenylethyl)-2,3,6,7-tetrahydrobenzopyran-4,7-dione.Four species were found to be different, having the enantiomer of apetalic acid, isoapetalic acid and a minor acid identified as the structural isomer of the latter.
