Check Digit Verification of cas no
The CAS Registry Mumber 1043252-32-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,3,2,5 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1043252-32:
(9*1)+(8*0)+(7*4)+(6*3)+(5*2)+(4*5)+(3*2)+(2*3)+(1*2)=99
99 % 10 = 9
So 1043252-32-9 is a valid CAS Registry Number.
