131470-48-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131470-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,7 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 131470-48:
(8*1)+(7*3)+(6*1)+(5*4)+(4*7)+(3*0)+(2*4)+(1*8)=99
99 % 10 = 9
So 131470-48-9 is a valid CAS Registry Number.
