Check Digit Verification of cas no
The CAS Registry Mumber 141885-69-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,8 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 141885-69:
(8*1)+(7*4)+(6*1)+(5*8)+(4*8)+(3*5)+(2*6)+(1*9)=150
150 % 10 = 0
So 141885-69-0 is a valid CAS Registry Number.
