Check Digit Verification of cas no
The CAS Registry Mumber 162990-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,9,9 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 162990-28:
(8*1)+(7*6)+(6*2)+(5*9)+(4*9)+(3*0)+(2*2)+(1*8)=155
155 % 10 = 5
So 162990-28-5 is a valid CAS Registry Number.
