Check Digit Verification of cas no
The CAS Registry Mumber 192199-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,1,9 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 192199-08:
(8*1)+(7*9)+(6*2)+(5*1)+(4*9)+(3*9)+(2*0)+(1*8)=159
159 % 10 = 9
So 192199-08-9 is a valid CAS Registry Number.
