131549-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131549-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,4 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 131549-98:
(8*1)+(7*3)+(6*1)+(5*5)+(4*4)+(3*9)+(2*9)+(1*8)=129
129 % 10 = 9
So 131549-98-9 is a valid CAS Registry Number.
