73522-63-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73522-63-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,2 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 73522-63:
(7*7)+(6*3)+(5*5)+(4*2)+(3*2)+(2*6)+(1*3)=121
121 % 10 = 1
So 73522-63-1 is a valid CAS Registry Number.

Perez C., Ana L.,Colin V., Micaela Del C.,Guerrero R., Carlos,Luz Cruz R., Ma. De La,Vivar R., Alfonzo Romo De

, p. 823 - 828 (1984)

A chemical investigation of Tithonia rotundifolia afforded seven new sesquiterpene lactones in addition to three known ones.The structures of the new compounds 3-acetyl-15-hydroxyleptocarpin, 15-hydroxyleptocarpin, and tirotundifolins A, B, C, D and E were established by spectroscopic and chemical means.Key Word Index - Tithonia rotundifolia; Compositae; Heliantheae; sesquiterpene lactones; heliangolides; eudesmanolides; 15-hydroxyleptocarpins; tirotundifolins.
