Check Digit Verification of cas no
The CAS Registry Mumber 1000933-25-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,9,3 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1000933-25:
(9*1)+(8*0)+(7*0)+(6*0)+(5*9)+(4*3)+(3*3)+(2*2)+(1*5)=84
84 % 10 = 4
So 1000933-25-4 is a valid CAS Registry Number.
