657-07-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 657-07-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.Calculate Digit Verification of CAS Registry Number 657-07:
(5*6)+(4*5)+(3*7)+(2*0)+(1*7)=78
78 % 10 = 8
So 657-07-8 is a valid CAS Registry Number.
