General Description
HCTU [1] is a novel aminium-based coupling reagent, analogous to HBTU, which in comparative studies was found to give superiort results to TBTU in the synthesis of difficult peptides [2], in hindered couplings [3], and cyclizations [4].The product number for this product was previously 01-62-0038.To obtain a certificate of analysis (CoA) of a lot that begins with the letter “A”, please select the option in the right hand menu “Request a COA for Lot#s starting with A”.
Check Digit Verification of cas no
The CAS Registry Mumber 330645-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,6,4 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 330645-87:
(8*3)+(7*3)+(6*0)+(5*6)+(4*4)+(3*5)+(2*8)+(1*7)=129
129 % 10 = 9
So 330645-87-9 is a valid CAS Registry Number.
