The CAS Registry Mumber 188905-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,0 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188905-91:
(8*1)+(7*8)+(6*8)+(5*9)+(4*0)+(3*5)+(2*9)+(1*1)=191
191 % 10 = 1
So 188905-91-1 is a valid CAS Registry Number.
