Check Digit Verification of cas no

The CAS Registry Mumber 73663-58-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,6 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73663-58:
(7*7)+(6*3)+(5*6)+(4*6)+(3*3)+(2*5)+(1*8)=148
148 % 10 = 8
So 73663-58-8 is a valid CAS Registry Number.

Dimerization of Phenylalanine: An Approach to Thiazoles and Oxazoles Involved S/O-Insertion

supporting information, p. 550 - 555 (2017/12/07)

We herein describe the development of a dimerization procedure for amino acids to prepare 2,5-disubstituted thiazoles and oxazoles in the presence of Na2S?9H2O and H2O, respectively. These approaches enabled the direct formation of five-membered ring systems bearing two different heteroatoms from two amino acid units. Mechanically, decarboxylation, deamination, S/O insertion, cyclization and gradient oxidation processes were involved in the oligomer formation. (Figure presented.).
