2128-61-2 Usage
Description
The leaves of Croton sparsijlorus Morung yield this noraporphine alkaloid which
crystallizes as colourless, slender needles from EtOH. Two hydroxyl groups and
an imino group are present and the base yields crystalline salts and derivatives,
e.g. the hydrochloride, [α]30D + 43° (H20); methiodide, m.p. 218°C (dec.); the
O,N-diacetyl derivative, m.p. 245°C and the triacetyl derivative, m.p. 196-7°C.
The N-methyl compound gives a crystalline methiodide, m.p. 236-8°C (dec.).
The structure has been established as 2-methoxy-l : 10-dihydroxynor aporphine.

Check Digit Verification of cas no
The CAS Registry Mumber 2128-61-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,2 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2128-61:
(6*2)+(5*1)+(4*2)+(3*8)+(2*6)+(1*1)=62
62 % 10 = 2
So 2128-61-2 is a valid CAS Registry Number.
