Check Digit Verification of cas no
The CAS Registry Mumber 112030-33-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,0,3 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 112030-33:
(8*1)+(7*1)+(6*2)+(5*0)+(4*3)+(3*0)+(2*3)+(1*3)=48
48 % 10 = 8
So 112030-33-8 is a valid CAS Registry Number.
