51021-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51021-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,0,2 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 51021-85:
(7*5)+(6*1)+(5*0)+(4*2)+(3*1)+(2*8)+(1*5)=73
73 % 10 = 3
So 51021-85-3 is a valid CAS Registry Number.

(Chemical Equation Presented) A facile method for N-deallylation at the amide nitrogen of peptides is described. One-pot deallylation of a substrate through ruthenium hydride-catalyzed terminal olefin isomerization and subsequent ozonolysis gave the corresponding deallylated product under mild conditions.
