112057-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112057-65-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,0,5 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 112057-65:
(8*1)+(7*1)+(6*2)+(5*0)+(4*5)+(3*7)+(2*6)+(1*5)=85
85 % 10 = 5
So 112057-65-5 is a valid CAS Registry Number.
