Check Digit Verification of cas no
The CAS Registry Mumber 1033942-68-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,3,9,4 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1033942-68:
(9*1)+(8*0)+(7*3)+(6*3)+(5*9)+(4*4)+(3*2)+(2*6)+(1*8)=135
135 % 10 = 5
So 1033942-68-5 is a valid CAS Registry Number.
