1085503-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1085503-20-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,5,5,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1085503-20:
(9*1)+(8*0)+(7*8)+(6*5)+(5*5)+(4*0)+(3*3)+(2*2)+(1*0)=133
133 % 10 = 3
So 1085503-20-3 is a valid CAS Registry Number.
