The CAS Registry Mumber 197805-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,8,0 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 197805-75:
(8*1)+(7*9)+(6*7)+(5*8)+(4*0)+(3*5)+(2*7)+(1*5)=187
187 % 10 = 7
So 197805-75-7 is a valid CAS Registry Number.
