Check Digit Verification of cas no
The CAS Registry Mumber 154185-85-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,1,8 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 154185-85:
(8*1)+(7*5)+(6*4)+(5*1)+(4*8)+(3*5)+(2*8)+(1*5)=140
140 % 10 = 0
So 154185-85-0 is a valid CAS Registry Number.
