83177-88-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83177-88-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,7 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83177-88:
(7*8)+(6*3)+(5*1)+(4*7)+(3*7)+(2*8)+(1*8)=152
152 % 10 = 2
So 83177-88-2 is a valid CAS Registry Number.

The coupling reaction of m-methoxystyrene (1) and 4-bromo-1-diazo-2-butanone (2) over Pd(OAc)2 gave trans and cis (ratio 7:1) cyclopropane derivatives 3a and 3b, which were used for the alkylation of 2-methylcyclopentane-1,3-dione to afford triketones 4a
