Check Digit Verification of cas no

The CAS Registry Mumber 91178-23-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,7 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91178-23:
(7*9)+(6*1)+(5*1)+(4*7)+(3*8)+(2*2)+(1*3)=133
133 % 10 = 3
So 91178-23-3 is a valid CAS Registry Number.

bis-allylic reactivity of the funicolides, 5,8(17)-diunsaturated briarane diterpenes of the sea pen Funiculina quadrangularis from the Tuscan archipelago, leading to 16-nortaxane derivatives

Guerriero,D'Ambrosio,Pietra

, p. 1465 - 1478 (1995)

Funicolides A-C (1-3), D (5), and E (7) and 7-epifunicolide A (4), new 5,8(17)-diunsaturated briarane diterpenes, as well as the known analogue brianthein W (6), were isolated from the pennatulacean coral Funiculina quadrangularis (Pallas, 1766) collected in the Tuscan archipelago. Easy degradation under oxidative and/or basic conditions served to assign the ester groups at C(2) or C(14), while revealing bis-allylic reactivity at C(7) with formation of 16-nortaxane derivatives.
