Check Digit Verification of cas no
The CAS Registry Mumber 173069-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,0,6 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 173069-40:
(8*1)+(7*7)+(6*3)+(5*0)+(4*6)+(3*9)+(2*4)+(1*0)=134
134 % 10 = 4
So 173069-40-4 is a valid CAS Registry Number.
