Check Digit Verification of cas no

The CAS Registry Mumber 1241901-39-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,9,0 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1241901-39:
(9*1)+(8*2)+(7*4)+(6*1)+(5*9)+(4*0)+(3*1)+(2*3)+(1*9)=122
122 % 10 = 2
So 1241901-39-2 is a valid CAS Registry Number.

Spiroheterocycles via regioselective cycloaddition reactions of nitrile oxides with 5-methylene-1H-pyrrol-2(5H)-ones

Beattie, Nicola J.,Francis, Craig L.,Liepa, Andris J.,Savage, G. Paul

experimental part, p. 445 - 451 (2010/08/06)

Substituted 5-methylene-1H-pyrrol-2(5H)-ones underwent a 1,3-dipolar cycloaddition reaction with nitrile oxides to give the corresponding spiro heterocycles. Critical to this reaction was the development of a biphasic system for base-induced dehydrohaloge
