Check Digit Verification of cas no
The CAS Registry Mumber 118149-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,1,4 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118149-28:
(8*1)+(7*1)+(6*8)+(5*1)+(4*4)+(3*9)+(2*2)+(1*8)=123
123 % 10 = 3
