Check Digit Verification of cas no

The CAS Registry Mumber 81784-14-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,8 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81784-14:
(7*8)+(6*1)+(5*7)+(4*8)+(3*4)+(2*1)+(1*4)=147
147 % 10 = 7
So 81784-14-7 is a valid CAS Registry Number.

THREE NEW SESQUITERPENE PHENOLS OF THE ENT-HERBERTANE CLASS FROM THE LIVERWORT HERBERTA ADUNCA

Matsuo, Akihiko,Yuki, Shunji,Nakayama, Mitsuru,Hayashi, Shuichi

, p. 463 - 466 (1982)

Three sesquiterpene phenols with an ent-herberatne skeleton have been isolated from the liverworth Herberta adunca, and the alucidation of their structures and absolue configurations has been achieved on the basis of the chemical and spectral evidence.

Structures of ent-Herbertane Sesquiterpenoids displaying Antifungal Properties from the Liverwort Herberta adunca

Matsua, Akihiko,Yuki, Shunji,Nakayama, Mitsuru

, p. 701 - 710 (2007/10/02)

Several aromatic sesquiterpenoids displaying antifungal propaerties have been isolated from the liverwort Herberta adunca together with a mother hydrocarbon with a novel irregular sesquiterpene skeleton, ent-herbertane, and their structures and absolute configurations have been determined on the basis of extensive degradation reactions and spectroscopic evidence.The biological activity is also described.
