Check Digit Verification of cas no
The CAS Registry Mumber 156115-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,1,1 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 156115-05:
(8*1)+(7*5)+(6*6)+(5*1)+(4*1)+(3*5)+(2*0)+(1*5)=108
108 % 10 = 8
So 156115-05-8 is a valid CAS Registry Number.
