146336-63-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146336-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,3,3 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 146336-63:
(8*1)+(7*4)+(6*6)+(5*3)+(4*3)+(3*6)+(2*6)+(1*3)=132
132 % 10 = 2
So 146336-63-2 is a valid CAS Registry Number.

A radical approach to the synthesis of (±)-supinidine

Intramolecular addition of α-sulfonyl radicals to triple bonds followed by addition of tin radicals to the resulting allylsulfones gave pyrrolizidine skeletons. Subsequent manipulations led to a formal synthesis of (±)-supinidine.
