83187-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83187-73-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,8 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83187-73:
(7*8)+(6*3)+(5*1)+(4*8)+(3*7)+(2*7)+(1*3)=149
149 % 10 = 9
So 83187-73-9 is a valid CAS Registry Number.
