189700-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189700-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,7,0 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 189700-19:
(8*1)+(7*8)+(6*9)+(5*7)+(4*0)+(3*0)+(2*1)+(1*9)=164
164 % 10 = 4
So 189700-19-4 is a valid CAS Registry Number.
