1032198-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1032198-12-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,2,1,9 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1032198-12:
(9*1)+(8*0)+(7*3)+(6*2)+(5*1)+(4*9)+(3*8)+(2*1)+(1*2)=111
111 % 10 = 1
So 1032198-12-1 is a valid CAS Registry Number.
