104684-70-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104684-70-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,8 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 104684-70:
(8*1)+(7*0)+(6*4)+(5*6)+(4*8)+(3*4)+(2*7)+(1*0)=120
120 % 10 = 0
So 104684-70-0 is a valid CAS Registry Number.
