81490-47-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81490-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,9 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81490-47:
(7*8)+(6*1)+(5*4)+(4*9)+(3*0)+(2*4)+(1*7)=133
133 % 10 = 3
So 81490-47-3 is a valid CAS Registry Number.
