67257-63-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67257-63-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,5 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67257-63:
(7*6)+(6*7)+(5*2)+(4*5)+(3*7)+(2*6)+(1*3)=150
150 % 10 = 0
So 67257-63-0 is a valid CAS Registry Number.

, 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
