22571-95-5 Usage
Description
This pyrrolizidine alkaloid occurs in the roots of Symphytum officinale Linn.
and is difficult to crystallize. The above structure has been proposed on the basis
of chemical degradation and spectroscopic evidence.
Definition
ChEBI: A but-2-enoate ester obtained by formal condensation of the carboxy group of (2E)-2-methylbut-2-enoic acid with the 1-hydroxy group of (1R,7aR)-7-({[(2S,3S)-2,3-dihydroxy-
-isopropylbutanoyl]oxy}methyl)-2,3,5,7a-tetrahydro-1H-pyrrolizin-1-ol.

Check Digit Verification of cas no
The CAS Registry Mumber 22571-95-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,5,7 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22571-95:
(7*2)+(6*2)+(5*5)+(4*7)+(3*1)+(2*9)+(1*5)=105
105 % 10 = 5
So 22571-95-5 is a valid CAS Registry Number.
