67662-53-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67662-53-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,6 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67662-53:
(7*6)+(6*7)+(5*6)+(4*6)+(3*2)+(2*5)+(1*3)=157
157 % 10 = 7
So 67662-53-7 is a valid CAS Registry Number.
