67553-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67553-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,5,5 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67553-01:
(7*6)+(6*7)+(5*5)+(4*5)+(3*3)+(2*0)+(1*1)=139
139 % 10 = 9
So 67553-01-9 is a valid CAS Registry Number.
