131251-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131251-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,5 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131251-89:
(8*1)+(7*3)+(6*1)+(5*2)+(4*5)+(3*1)+(2*8)+(1*9)=93
93 % 10 = 3
So 131251-89-3 is a valid CAS Registry Number.
