131248-90-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131248-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,4 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131248-90:
(8*1)+(7*3)+(6*1)+(5*2)+(4*4)+(3*8)+(2*9)+(1*0)=103
103 % 10 = 3
So 131248-90-3 is a valid CAS Registry Number.
