Check Digit Verification of cas no

The CAS Registry Mumber 714956-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,4,9,5 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 714956-91:
(8*7)+(7*1)+(6*4)+(5*9)+(4*5)+(3*6)+(2*9)+(1*1)=189
189 % 10 = 9
So 714956-91-9 is a valid CAS Registry Number.

Synthesis of jaspaquinol and effect on viability of normal and malignant bladder epithelial cell lines

Demotie, Alexandre,Fairlamb, Ian J.S.,Lu, Feng-Ju,Shaw, Nicola J.,Spencer, Peter A.,Southgate, Jennifer

, p. 2883 - 2887 (2007/10/03)

The synthesis of jaspaquinol 1, a monocyclic diterpene-benzenoid, is reported. Two synthetic routes to this natural product have been developed. The first, utilises a difunctional terpene derivative containing different leaving groups, facilitating the selective introduction of the cyclohexenyl and benzenoid fragments. The alternative route employs a regiospecific Stille cross-coupling reaction to introduce the cyclohexenyl fragment, which occurs without allylic transposition. Preliminary data shows the cell viability of 1 against normal and malignant human bladder epithelial cell lines.
