1333380-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1333380-20-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,3,8 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1333380-20:
(9*1)+(8*3)+(7*3)+(6*3)+(5*3)+(4*8)+(3*0)+(2*2)+(1*0)=123
123 % 10 = 3
So 1333380-20-3 is a valid CAS Registry Number.

The first asymmetric synthesis of natural indole alkaloid (+)-decursivine was accomplished. The key step involves the PIFA-mediated intramolecular [3 + 2] cycloaddition of 5-hydroxytryptophan with a substituted cinnamamide in a highly diastereoselective m
