Check Digit Verification of cas no
The CAS Registry Mumber 162331-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,3,3 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 162331-09:
(8*1)+(7*6)+(6*2)+(5*3)+(4*3)+(3*1)+(2*0)+(1*9)=101
101 % 10 = 1
So 162331-09-1 is a valid CAS Registry Number.
