122016-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122016-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,1 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 122016-57:
(8*1)+(7*2)+(6*2)+(5*0)+(4*1)+(3*6)+(2*5)+(1*7)=73
73 % 10 = 3
So 122016-57-3 is a valid CAS Registry Number.
