500148-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 500148-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,1,4 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 500148-58:
(8*5)+(7*0)+(6*0)+(5*1)+(4*4)+(3*8)+(2*5)+(1*8)=103
103 % 10 = 3
So 500148-58-3 is a valid CAS Registry Number.
