83516-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83516-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,1 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83516-40:
(7*8)+(6*3)+(5*5)+(4*1)+(3*6)+(2*4)+(1*0)=129
129 % 10 = 9
So 83516-40-9 is a valid CAS Registry Number.
