2160-57-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2160-57-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.Calculate Digit Verification of CAS Registry Number 2160-57:
(6*2)+(5*1)+(4*6)+(3*0)+(2*5)+(1*7)=58
58 % 10 = 8
So 2160-57-8 is a valid CAS Registry Number.
