104858-32-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104858-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,5 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104858-32:
(8*1)+(7*0)+(6*4)+(5*8)+(4*5)+(3*8)+(2*3)+(1*2)=124
124 % 10 = 4
So 104858-32-4 is a valid CAS Registry Number.
