Check Digit Verification of cas no

The CAS Registry Mumber 146721-08-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,7,2 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 146721-08:
(8*1)+(7*4)+(6*6)+(5*7)+(4*2)+(3*1)+(2*0)+(1*8)=126
126 % 10 = 6
So 146721-08-6 is a valid CAS Registry Number.

Synthesis and Insecticidal Activity of Sesquilignan Analogs with 2-Alkyl-6-methoxy-3-(3,4-methylenedioxyphenyl)-1,4-benzodioxanyl Group

Yamauchi, Satoshi,Taniguchi, Eiji

, p. 1751 - 1759 (2007/10/02)

The methoxymethyl group of the 6-methoxy-2-methoxymethyl-3-(3,4-methylenedioxyphenyl)-1,4-benzodioxan-7-yl moiety of insecticidal lignans of Phryma was modified with several alkyl groups to evaluate the effect on activity of the substituents.The assay results make it evident that this activity was significantly modified by the chain length or bulkiness of the alkyl groups and that the oxygen atom of the methoxymethyl group was fairly important for enhancing the activity.
