17172-16-6 Usage
Description
The aerial parts of Vinca erecta yield this imidazolidinocarbazole alkaloid which
has been characterized as the epi-base formed on heating with NaOMe in NaOH
and giving a crystalline hydrochloride, m.p. 2S7-9°C (dec.); [α]D + 92.1°
(MeOH). Treatment of the alkaloid with lead acetate gives the dehydro derivative,
m.p. 188-1910C; [α]D + 62° (MeOH).
Occurrence
The absolute configuration of this alkaloid has now been established from spectroscopic data.

Check Digit Verification of cas no
The CAS Registry Mumber 17172-16-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,7 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17172-16:
(7*1)+(6*7)+(5*1)+(4*7)+(3*2)+(2*1)+(1*6)=96
96 % 10 = 6
So 17172-16-6 is a valid CAS Registry Number.
