67931-49-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67931-49-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,3 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 67931-49:
(7*6)+(6*7)+(5*9)+(4*3)+(3*1)+(2*4)+(1*9)=161
161 % 10 = 1
So 67931-49-1 is a valid CAS Registry Number.
