Check Digit Verification of cas no

The CAS Registry Mumber 137559-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,5 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137559-30:
(8*1)+(7*3)+(6*7)+(5*5)+(4*5)+(3*9)+(2*3)+(1*0)=149
149 % 10 = 9
So 137559-30-9 is a valid CAS Registry Number.

Design and synthesis of Fmoc-SPPS-ready iodoarene amino acid pre-catalysts and their reactivity in the catalytic oxytosylation of ketones

Brummel, Beau R.,Giambalvo, Lauren N.,Gross, Kristopher G.,Kobra, Khadijatul,Lex, Timothy R.,McMillen, Colin D.,Panda, Soham,Pennington, William T.,Swasy, Maria I.,Whitehead, Daniel C.

, (2020)

A small suite of iodo-aryl amide containing amino acids were synthesized and assessed as catalysts for the hypervalent iodine(III) mediated α-oxytosylation of ketones. The efficiency of each catalyst was determined by comparing the relative rates of catalysis in the direct α-oxytosylation of propiophenone. In addition, these catalysts can be easily converted to congeners that are suitable for Fmoc-solid phase peptide synthesis for facile incorporation into a chiral peptide framework. This work facilitates the broader goal of our program to develop peptide-based enantioselective catalysts for hypervalent iodine chemistry.
