Check Digit Verification of cas no

The CAS Registry Mumber 177659-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,6,5 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 177659-56:
(8*1)+(7*7)+(6*7)+(5*6)+(4*5)+(3*9)+(2*5)+(1*6)=192
192 % 10 = 2
So 177659-56-2 is a valid CAS Registry Number.

Destruxin analogues: Depsi peptidic bond replacement by amide bond

Cavelier,Jacquier,Mercadier,Verducci

, p. 6173 - 6186 (2007/10/03)

In order to determine the importance of the depsi bond present in natural destruxins, we have investigated the replacement of this ester bond by an amide bond, leading to a new family of analogues. Synthesis of six specific members of this new class of compounds is reported. Since none of these cyclopeptides showed any biological activity, we undoubtedly proved that the depside group is a requisite for insecticide effect.
