Check Digit Verification of cas no

The CAS Registry Mumber 913639-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,3,6,3 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 913639-90:
(8*9)+(7*1)+(6*3)+(5*6)+(4*3)+(3*9)+(2*9)+(1*0)=184
184 % 10 = 4
So 913639-90-4 is a valid CAS Registry Number.

Peptide-Chain Elongation Using Unprotected Amino Acids in a Micro-Flow Reactor

Fuse, Shinichiro,Masuda, Koshiro,Otake, Yuma,Nakamura, Hiroyuki

, p. 15091 - 15097 (2019/11/13)

Conventional peptide synthesis requires a deprotection step after each amidation step, which decreases synthetic efficiency. Therefore, peptide synthesis using unprotected amino acids is considered an ideal approach. Here, we report peptide chain elongati
