67522-05-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67522-05-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,5,2 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 67522-05:
(7*6)+(6*7)+(5*5)+(4*2)+(3*2)+(2*0)+(1*5)=128
128 % 10 = 8
So 67522-05-8 is a valid CAS Registry Number.
