142846-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142846-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,4 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142846-57:
(8*1)+(7*4)+(6*2)+(5*8)+(4*4)+(3*6)+(2*5)+(1*7)=139
139 % 10 = 9
So 142846-57-9 is a valid CAS Registry Number.

Synthesis of doubly cross-linked cyclic hexapeptides
Bailey,Carter,Clarke,Crofts,Tyszka,Smith,Ward
, p. 3211 - 3214 (2007/10/02)
Cyclic hexapeptides in which adjacent N(ε)-nitrogens of cyclo-(Lys-Lys-Gly)2 are cross-linked by p-xylyl or (CH2)6 units have been prepared. The key steps in the syntheses of these novel types of peptide were the use of tosyl (or, le
