190248-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 190248-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,2,4 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 190248-08:
(8*1)+(7*9)+(6*0)+(5*2)+(4*4)+(3*8)+(2*0)+(1*8)=129
129 % 10 = 9
So 190248-08-9 is a valid CAS Registry Number.
