Check Digit Verification of cas no

The CAS Registry Mumber 196697-06-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,6,9 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 196697-06:
(8*1)+(7*9)+(6*6)+(5*6)+(4*9)+(3*7)+(2*0)+(1*6)=200
200 % 10 = 0
So 196697-06-0 is a valid CAS Registry Number.

First total synthesis of prionoid E, A bioactive rearranged secoabietane diterpene quinone from Salvia prionitis

Deng, Fei,Xu, Jun,Zhao, Min,Liu, Hong-Ying,Ye, Yang,Zhang, Jin-Sheng

, p. 1326 - 1334 (2011)

The first total synthesis of prionoid E (1), a rearranged secoabietane diterpene quinone isolated from Salvia prionitis, was achieved efficiently by means of Wacker oxidation (Scheme 5) and aldol condensation (Scheme 7) as the key steps in the synthetic sequence. Thus 1 was prepared in 15 steps in 3.7% yield starting on one hand from anisole (=methoxybenzene) and methylsuccinic anhydride (=dihydro-3-methylfuran-2,5-dione) via 4 (Scheme 3 and 5), and on the other hand from 2-hydroxy-2-methylpropanoic acid via 5 (Scheme 6).
