67603-32-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67603-32-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,0 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67603-32:
(7*6)+(6*7)+(5*6)+(4*0)+(3*3)+(2*3)+(1*2)=131
131 % 10 = 1
So 67603-32-1 is a valid CAS Registry Number.
