Check Digit Verification of cas no
The CAS Registry Mumber 189807-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,8,0 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 189807-28:
(8*1)+(7*8)+(6*9)+(5*8)+(4*0)+(3*7)+(2*2)+(1*8)=191
191 % 10 = 1
So 189807-28-1 is a valid CAS Registry Number.
