131172-48-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131172-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,7 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 131172-48:
(8*1)+(7*3)+(6*1)+(5*1)+(4*7)+(3*2)+(2*4)+(1*8)=90
90 % 10 = 0
So 131172-48-0 is a valid CAS Registry Number.
