189384-00-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189384-00-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,8 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189384-00:
(8*1)+(7*8)+(6*9)+(5*3)+(4*8)+(3*4)+(2*0)+(1*0)=177
177 % 10 = 7
So 189384-00-7 is a valid CAS Registry Number.
