Check Digit Verification of cas no
The CAS Registry Mumber 191589-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,5,8 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 191589-06:
(8*1)+(7*9)+(6*1)+(5*5)+(4*8)+(3*9)+(2*0)+(1*6)=167
167 % 10 = 7
