Check Digit Verification of cas no
The CAS Registry Mumber 154185-86-1 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 154185-86:
(8*1)+(7*5)+(6*4)+(5*1)+(4*8)+(3*5)+(2*8)+(1*6)=141
141 % 10 = 1
So 154185-86-1 is a valid CAS Registry Number.
