Check Digit Verification of cas no

The CAS Registry Mumber 294201-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,4,2,0 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 294201-15:
(8*2)+(7*9)+(6*4)+(5*2)+(4*0)+(3*1)+(2*1)+(1*5)=123
123 % 10 = 3
So 294201-15-3 is a valid CAS Registry Number.

Cyclols Revisited: Facile Synthesis of Medium-Sized Cyclic Peptides

Mendoza-Sanchez, Rodrigo,Corless, Victoria B.,Nguyen, Q. Nhu N.,Bergeron-Brlek, Milan,Frost, John,Adachi, Shinya,Tantillo, Dean J.,Yudin, Andrei K.

, p. 13319 - 13322 (2017)

Medium-sized rings, particularly the corresponding cyclic peptides, are challenging synthetic targets. In the present study, we report an approach to medium-sized cyclic peptides through targeted formation and collapse of cyclol intermediates. This methodology operates on β-amino imides derived from 2,5-diketopiperazines and offers a straightforward transition from frequently examined scaffolds in drug discovery to a rarely visited class of medium-sized rings.
