19448-99-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19448-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,4 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19448-99:
(7*1)+(6*9)+(5*4)+(4*4)+(3*8)+(2*9)+(1*9)=148
148 % 10 = 8
So 19448-99-8 is a valid CAS Registry Number.
