123190-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123190-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,1,9 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123190-08:
(8*1)+(7*2)+(6*3)+(5*1)+(4*9)+(3*0)+(2*0)+(1*8)=89
89 % 10 = 9
So 123190-08-9 is a valid CAS Registry Number.
