104512-82-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104512-82-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,5,1 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104512-82:
(8*1)+(7*0)+(6*4)+(5*5)+(4*1)+(3*2)+(2*8)+(1*2)=85
85 % 10 = 5
So 104512-82-5 is a valid CAS Registry Number.
