180923-15-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 180923-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,9,2 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180923-15:
(8*1)+(7*8)+(6*0)+(5*9)+(4*2)+(3*3)+(2*1)+(1*5)=133
133 % 10 = 3
So 180923-15-3 is a valid CAS Registry Number.

Peptide ligation by chemoselective aminonitrile coupling in water
Canavelli, Pierre,Islam, Saidul,Powner, Matthew W.
, p. 546 - 549 (2019/07/31)
Amide bond formation is one of the most important reactions in both chemistry and biology1–4, but there is currently no chemical method of achieving α-peptide ligation in water that tolerates all of the 20 proteinogenic amino acids at the pepti
