81902-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81902-76-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,0 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.Calculate Digit Verification of CAS Registry Number 81902-76:
(7*8)+(6*1)+(5*9)+(4*0)+(3*2)+(2*7)+(1*6)=133
133 % 10 = 3
So 81902-76-3 is a valid CAS Registry Number.
