Check Digit Verification of cas no
The CAS Registry Mumber 109023-77-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,2 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 109023-77:
(8*1)+(7*0)+(6*9)+(5*0)+(4*2)+(3*3)+(2*7)+(1*7)=100
100 % 10 = 0
So 109023-77-0 is a valid CAS Registry Number.
