Description
BOC-HIS-NHNH2 is a protected amino acid derivative of histidine, featuring a BOC (tert-butoxycarbonyl) protecting group and an additional NHNH2 group attached to the amino group. This modification allows for the prevention of unwanted side reactions in peptide synthesis and enables mild cleavage conditions to reveal the free amino group.

Check Digit Verification of cas no
The CAS Registry Mumber 42002-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,0 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42002-05:
(7*4)+(6*2)+(5*0)+(4*0)+(3*2)+(2*0)+(1*5)=51
51 % 10 = 1
So 42002-05-1 is a valid CAS Registry Number.

Amino Acid Functionalized Organotin Trichlorides and Their Tin Sulfide Clusters
Engel, Annikka,Dehnen, Stefanie
, (2019/08/02)
We present a new synthesis of functionalized tin sulfide clusters via organotin trichlorides with boc-protected amino acids (RAAcSnCl3). In this work we used non-polar (alanine, valine, leucine, phenylalanine and methionine), polar/neutral (serine and tyrosine) and basic (histidine) amino acids. We obtained single crystals from a Boc-protected valine derivative of the originally used organotin trichloride R1SnCl3 [R1 = CMe2CH2C(O)Me] and determined its structure by means of X-ray diffraction. A subsequent reaction with sulfide sources led to a variety of respective cluster structures. By using either (Me3Si)2S or Na2S, the reaction product turns out to be the defect-heterocubane cluster [(RAAcSn)3S4Cl] or the “doppeldecker”-type cluster [(RAAcSn)4S6], respectively, according to 119Sn NMR spectroscopy.
