99880-61-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99880-61-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,8 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99880-61:
(7*9)+(6*9)+(5*8)+(4*8)+(3*0)+(2*6)+(1*1)=202
202 % 10 = 2
So 99880-61-2 is a valid CAS Registry Number.

Chemoenzymatic peptide synthesis is potentially the most cost-efficient technology for the synthesis of short and medium-sized peptides with some important advantages. For instance, stoichiometric amounts of expensive coupling reagents are not required an
