173271-21-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173271-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,2,7 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 173271-21:
(8*1)+(7*7)+(6*3)+(5*2)+(4*7)+(3*1)+(2*2)+(1*1)=121
121 % 10 = 1
So 173271-21-1 is a valid CAS Registry Number.
