Check Digit Verification of cas no

The CAS Registry Mumber 1280219-35-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,2,1 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1280219-35:
(9*1)+(8*2)+(7*8)+(6*0)+(5*2)+(4*1)+(3*9)+(2*3)+(1*5)=133
133 % 10 = 3
So 1280219-35-3 is a valid CAS Registry Number.

A [3 +2] Dipolar cycloaddition route to 3-hydroxy-3-alkyl oxindoles: An approach to pyrrolidinoindoline alkaloids

Singh, Anand,Roth, Gregory P.

, p. 2118 - 2121 (2011)

A [3+2] cycloaddition approach to the 3-hydroxy-3-alkyl oxindole scaffold is described. Isoxazolines obtained by cycloaddition of nitrile oxide 3 with 3-methylene oxindoles were elaborated to 3-hydroxy-3-cyanomethyl oxindoles employing a one-pot protocol
