189999-47-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189999-47-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,9,9 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189999-47:
(8*1)+(7*8)+(6*9)+(5*9)+(4*9)+(3*9)+(2*4)+(1*7)=241
241 % 10 = 1
So 189999-47-1 is a valid CAS Registry Number.
