Check Digit Verification of cas no

The CAS Registry Mumber 132922-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,2 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132922-67:
(8*1)+(7*3)+(6*2)+(5*9)+(4*2)+(3*2)+(2*6)+(1*7)=119
119 % 10 = 9
So 132922-67-9 is a valid CAS Registry Number.

A total synthetic route for two natural dihydrostilbenes with significant cytotoxicity toward human cancer cell lines, (3-(2-(7-methoxybenzo[d][1,3] dioxol-5-yl)ethyl)phenol 1a and 6-(3-hydroxyphenethyl)benzo[d][1,3]dioxol-4-ol 1b), which were isolated from Bulbophyllum odoratissimum Lind1, was developed via Wittig-Horner reaction. The natural products 1a and 1b were obtained in 28% and 20% overall yield, respectively. Additionally, nine analogues, 1c-1k, of the two natural dihydrostilbenes were synthesized and evaluated for their anti-proliferative activity against human SGC-7901, KB and HT-1080 cell lines by MTT assay. The activities of 1c and 1d were in the same range as those of the natural products 1a and 1b.
