19741-46-9 Usage
Description
Spiraea japonica L. fil. yields a series of closely related alkaloids, Spiradines A-G.
This particular base is characterized as the methiodide which forms orthorhombic crystals decomposing above 330°C; the O-acetate, m.p. 21S-6°C and the N_x0002_acetyl derivative, m.p. 173-S°C. With NaBH4 in MeOH it yields Spiradine B
(q.v.) while on catalytic hydrogenation in EtOH it forms the dihydro derivative,
m.p. 291-2°C in which the exocyclic methylene group is reduced. The crystal
structure has been determined by X-ray analysis of the methiodide which
crystallizes in the space group P2 12121 with a = 14.04, b = IS.88, c = 8.SS A
and Z = 4.

Check Digit Verification of cas no
The CAS Registry Mumber 19741-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,4 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 19741-46:
(7*1)+(6*9)+(5*7)+(4*4)+(3*1)+(2*4)+(1*6)=129
129 % 10 = 9
So 19741-46-9 is a valid CAS Registry Number.
