Check Digit Verification of cas no
The CAS Registry Mumber 189563-97-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,5,6 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189563-97:
(8*1)+(7*8)+(6*9)+(5*5)+(4*6)+(3*3)+(2*9)+(1*7)=201
201 % 10 = 1
So 189563-97-1 is a valid CAS Registry Number.
