82861-09-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82861-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,6 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82861-09:
(7*8)+(6*2)+(5*8)+(4*6)+(3*1)+(2*0)+(1*9)=144
144 % 10 = 4
So 82861-09-4 is a valid CAS Registry Number.
