77220-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77220-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,2 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77220-03:
(7*7)+(6*7)+(5*2)+(4*2)+(3*0)+(2*0)+(1*3)=112
112 % 10 = 2
So 77220-03-2 is a valid CAS Registry Number.

Regiochemical aspects associated with the intramolecular 1,3-dipolar cycloaddition reactions of munchnone derivatives
Padwa, Albert,Gingrich, Henry L.,Lim, Richard
, p. 3419 - 3422 (2007/10/02)
The regioselectivity of the internal cycloaddition of a series of N-(o-allylphenyl) substituted munchnones has been found to be markedly dependent on the substituent groups present.
