171503-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 171503-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,5,0 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 171503-39:
(8*1)+(7*7)+(6*1)+(5*5)+(4*0)+(3*3)+(2*3)+(1*9)=112
112 % 10 = 2
So 171503-39-2 is a valid CAS Registry Number.
