5688-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5688-65-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,8 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5688-65:
(6*5)+(5*6)+(4*8)+(3*8)+(2*6)+(1*5)=133
133 % 10 = 3
So 5688-65-3 is a valid CAS Registry Number.
