Check Digit Verification of cas no

The CAS Registry Mumber 1311508-42-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,1,5,0 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1311508-42:
(9*1)+(8*3)+(7*1)+(6*1)+(5*5)+(4*0)+(3*8)+(2*4)+(1*2)=105
105 % 10 = 5
So 1311508-42-5 is a valid CAS Registry Number.

Design, synthesis and biological activity of peptidomimetic analogs of insect allatostatins

Xie, Yong,Kai, Zhen Peng,Tobe, Stephen S.,Deng, Xi Le,Ling, Yun,Wu, Xiao Qin,Huang, Juan,Zhang, Li,Yang, Xin Ling

Allatostatins (ASTs) comprise a family of insect neuropeptides isolated from cockroaches and found to inhibit the production of juvenile hormone (JH) by the corpora allata (CA). For this reason, the ASTs can be regarded as possible IGR candidates for pest control. Six peptidomimetic analogs according to the C-terminal pentapeptide of ASTs were prepared by solid-phase organic synthetic methods in an attempt to obtain new simple substitution agents. Assays of inhibition of JH biosynthesis in vitro by corpora allata from the cockroach Diploptera punctata showed that the activity of analog I (IC50: 0.09 μM) was more active than that of the C-terminal pentapeptide (Tyr-Xaa-Phe-Gly-Leu-NH2, IC50: 0.13 μM) it mimicked and the activity of the analog II (IC50: 0.13 μM) proved roughly equivalent to the C-terminal pentapeptide. The results indicate that a new simple mimicry for Tyr-Xaa-Phe-Gly has been discovered; analog I may be a novel compound candidate for potential IGRs. This study will be useful for the design of new AST analogs for insect management.
