Check Digit Verification of cas no

The CAS Registry Mumber 1237740-64-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,7,4 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1237740-64:
(9*1)+(8*2)+(7*3)+(6*7)+(5*7)+(4*4)+(3*0)+(2*6)+(1*4)=155
155 % 10 = 5
So 1237740-64-5 is a valid CAS Registry Number.

, p. 2394 - 2400 (2012/02/04)

Three series of novel 1,5-diphenyl-1-pentanone derivatives were designed and synthesized. Their structures were characterized by IR, 1H NMR techniques, and elemental analysis. The insecticidal activities of the new compounds were preliminarily evaluated. The bioassay results indicated that the compounds X11-X30 displayed better aphicidal activity against Aphis gossypii than compounds X1-X10 and the lead compound (E)-1,5-diphenyl-1-penten-1-one (A). The inhibitory rates of compounds X6 and X29 were 100% against Plutella xylostella (L.) at 600 mg·L-1. Compounds X12, X13, X19, X24, X25, X26 and X27 showed higher insecticidal activity against Tetranychus cinnabarinus (Boisduval) at 600 mg·L-1 than the lead compound (A).
