81836-01-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81836-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,3 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81836-01:
(7*8)+(6*1)+(5*8)+(4*3)+(3*6)+(2*0)+(1*1)=133
133 % 10 = 3
So 81836-01-3 is a valid CAS Registry Number.
