67688-19-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67688-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,8 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 67688-19:
(7*6)+(6*7)+(5*6)+(4*8)+(3*8)+(2*1)+(1*9)=181
181 % 10 = 1
So 67688-19-1 is a valid CAS Registry Number.
