81381-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81381-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,8 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81381-85:
(7*8)+(6*1)+(5*3)+(4*8)+(3*1)+(2*8)+(1*5)=133
133 % 10 = 3
So 81381-85-3 is a valid CAS Registry Number.
