40815-79-0 Usage

Preparation

Preparation by thermal Claisen rearrangement of 5-(allyloxy)-2-hydroxyacetophenone without solvent at 200–220° (36%) or at 220–230° (74–75%).

Check Digit Verification of cas no

The CAS Registry Mumber 40815-79-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,1 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40815-79:
(7*4)+(6*0)+(5*8)+(4*1)+(3*5)+(2*7)+(1*9)=110
110 % 10 = 0
So 40815-79-0 is a valid CAS Registry Number.
