Check Digit Verification of cas no

The CAS Registry Mumber 1161015-95-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,1,0,1 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1161015-95:
(9*1)+(8*1)+(7*6)+(6*1)+(5*0)+(4*1)+(3*5)+(2*9)+(1*5)=107
107 % 10 = 7
So 1161015-95-7 is a valid CAS Registry Number.

A new and general method for the synthesis of tripeptide aldehydes based on the multi-component Ugi reaction

Mroczkiewicz, Micha?,Ostaszewski, Ryszard

, p. 4025 - 4034 (2009)

Tripeptide aldehydes, such as Z-Leu-Leu-Leu-H (MG-132), are an important class of compounds due to their biological activity. A new, general method for the synthesis of tripeptide aldehydes based on the multi-component Ugi reaction was developed. A careful choice of isocyanides makes it possible to obtain tripeptide precursors whose functionalization led to target structures. This method can be used for the preparation of tripeptide aldehydes with non-natural amino acid side chains.
