690-60-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 690-60-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 690-60:
(5*6)+(4*9)+(3*0)+(2*6)+(1*0)=78
78 % 10 = 8
So 690-60-8 is a valid CAS Registry Number.
