67013-98-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67013-98-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,0,1 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 67013-98:
(7*6)+(6*7)+(5*0)+(4*1)+(3*3)+(2*9)+(1*8)=123
123 % 10 = 3
So 67013-98-3 is a valid CAS Registry Number.
