58656-05-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 58656-05-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,6,5 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.Calculate Digit Verification of CAS Registry Number 58656-05:
(7*5)+(6*8)+(5*6)+(4*5)+(3*6)+(2*0)+(1*5)=156
156 % 10 = 6
So 58656-05-6 is a valid CAS Registry Number.
