Check Digit Verification of cas no
The CAS Registry Mumber 189068-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,6 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 189068-22:
(8*1)+(7*8)+(6*9)+(5*0)+(4*6)+(3*8)+(2*2)+(1*2)=172
172 % 10 = 2
