Check Digit Verification of cas no
The CAS Registry Mumber 203056-15-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,0,5 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 203056-15:
(8*2)+(7*0)+(6*3)+(5*0)+(4*5)+(3*6)+(2*1)+(1*5)=79
79 % 10 = 9
So 203056-15-9 is a valid CAS Registry Number.
