Check Digit Verification of cas no

The CAS Registry Mumber 1256911-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,9,1 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1256911-71:
(9*1)+(8*2)+(7*5)+(6*6)+(5*9)+(4*1)+(3*1)+(2*7)+(1*1)=163
163 % 10 = 3
So 1256911-71-3 is a valid CAS Registry Number.

Spirodiclofen analogues as potential lipid biosynthesis inhibitors: A convenient synthesis, biological evaluation, and structure-activity relationship

Ke, Shaoyong,Sun, Tingting,Zhang, Zhigang,Zhang, Ya-Ni,Liang, Ying,Wang, Kaimei,Yang, Ziwen

experimental part, p. 2315 - 2321 (2010/11/16)

Twenty spirodiclofen analogues have been designed and conveniently synthesized via three steps including esterification, one-pot heterocyclization, and acylation reactions. The target molecules have been identified on the basis of analytical spectra (1H NMR, 13C NMR and ESI-MS) data. All newly synthesized compounds have been screened for their potential insecticidal and herbicidal activity by standard method. The preliminary assays indicated that some of analogues displayed moderate to good insecticidal activity against Plutella xylostella compared with spirodiclofen, and some compounds showed obvious activity against Brassica chinensis. Structure-activity relationship (SAR) is also discussed based on the experimental data.
