Check Digit Verification of cas no

The CAS Registry Mumber 91896-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,9 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91896-98:
(7*9)+(6*1)+(5*8)+(4*9)+(3*6)+(2*9)+(1*8)=189
189 % 10 = 9
So 91896-98-9 is a valid CAS Registry Number.

TRANSANNULAR CYCLIZATION OF HELIANGOLIDES

Teresa, J. de Pascual,Gonzalez, M. S.,Caballero, M. C.,Parra, T.,Bellido, I. S.

, p. 821 - 824 (2007/10/02)

4,5-cis-3β-Acetoxygermacranolide by treatment with BF3.OEt2, gave a mixture of 2-acetoxycadin-3,8,11(13)-trien-12-oic and 2-acetoxymuurol-3,8,11(13)-trien-12-oic acids, while 4,5-cis-1,10-epoxy-3β-hydroxygermacranolide gave the eudesmanolide tuberiferin.

SESQUITERPENIC ACIDS FROM LEUCANTHEMOPSIS PULVERULENTA

Teresa, J. de Pascual,Valle, M. A. Moreno,Gonzalez, M. S.,Bellido, I. S.

, p. 2189 - 2195 (2007/10/02)

From Leucanthemopsis pulverulenta (Compositae) ten new sesquiterpenic acids have been isolated.Their structures and absolute stereochemistry were assigned by spectral and chemical evidence; they are the first carboxylic acid members of the cadinane and munrolane series to be found in a natural source.
