Sesbania drummondii yields this spiro alkaloid. The base yields colourless rods from EtOH and is dextrorotatory with a specific rotation of [α]D23 + 14.6° (c 0.56, MeOH).
Check Digit Verification of cas no
The CAS Registry Mumber 70521-94-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,2 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70521-94:
(7*7)+(6*0)+(5*5)+(4*2)+(3*1)+(2*9)+(1*4)=107
107 % 10 = 7
So 70521-94-7 is a valid CAS Registry Number.
