84638-16-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84638-16-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,3 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 84638-16:
(7*8)+(6*4)+(5*6)+(4*3)+(3*8)+(2*1)+(1*6)=154
154 % 10 = 4
So 84638-16-4 is a valid CAS Registry Number.

Synthesis of (+/-)-Norruspoline
Herbert, Richard B.,Wormald, Peter C.
, p. 3001 - 3010 (2007/10/02)
Three interesting pyrrolidine alkaloids, ruspolinone (1), norruspolinone (2) and norruspoline (7), have been isolated from Ruspolia hyperecratiformis M.R. (Acanthaceae).Norruspolinone (2) has been shown to be an early precursor in the biosynthesis of the
