Check Digit Verification of cas no
The CAS Registry Mumber 112042-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,0,4 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 112042-03:
(8*1)+(7*1)+(6*2)+(5*0)+(4*4)+(3*2)+(2*0)+(1*3)=52
52 % 10 = 2
So 112042-03-2 is a valid CAS Registry Number.
