Check Digit Verification of cas no
The CAS Registry Mumber 152231-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,2,3 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 152231-17:
(8*1)+(7*5)+(6*2)+(5*2)+(4*3)+(3*1)+(2*1)+(1*7)=89
89 % 10 = 9
So 152231-17-9 is a valid CAS Registry Number.
