Check Digit Verification of cas no
The CAS Registry Mumber 155601-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,0 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 155601-03:
(8*1)+(7*5)+(6*5)+(5*6)+(4*0)+(3*1)+(2*0)+(1*3)=109
109 % 10 = 9
So 155601-03-9 is a valid CAS Registry Number.
