71980-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71980-73-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,8 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71980-73:
(7*7)+(6*1)+(5*9)+(4*8)+(3*0)+(2*7)+(1*3)=149
149 % 10 = 9
So 71980-73-9 is a valid CAS Registry Number.
