Check Digit Verification of cas no
The CAS Registry Mumber 189016-90-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,1 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189016-90:
(8*1)+(7*8)+(6*9)+(5*0)+(4*1)+(3*6)+(2*9)+(1*0)=158
158 % 10 = 8
So 189016-90-8 is a valid CAS Registry Number.
