427881-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 427881-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,7,8,8 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 427881-22:
(8*4)+(7*2)+(6*7)+(5*8)+(4*8)+(3*1)+(2*2)+(1*2)=169
169 % 10 = 9
So 427881-22-9 is a valid CAS Registry Number.

A new method for rapid solution synthesis of shorter peptides by use of PyBOP
Hoeg-Jensen,Havsteen Jakobsen,Holm
, p. 6387 - 6390 (2007/10/02)
By using PyBOP promoted coupling of Fmoc protected amino acids, and adopting the deprotection/washing procedure of the Fmoc Amino Acid Chloride Solution Technique (FAACST), a sample of [leucine5] enkephalin has been synthesized in a rapid, cont
