Check Digit Verification of cas no
The CAS Registry Mumber 189358-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,5 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189358-20:
(8*1)+(7*8)+(6*9)+(5*3)+(4*5)+(3*8)+(2*2)+(1*0)=181
181 % 10 = 1
So 189358-20-1 is a valid CAS Registry Number.
