Check Digit Verification of cas no
The CAS Registry Mumber 119581-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,5,8 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 119581-52:
(8*1)+(7*1)+(6*9)+(5*5)+(4*8)+(3*1)+(2*5)+(1*2)=141
141 % 10 = 1
So 119581-52-1 is a valid CAS Registry Number.
