Check Digit Verification of cas no
The CAS Registry Mumber 289709-40-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,7,0 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 289709-40:
(8*2)+(7*8)+(6*9)+(5*7)+(4*0)+(3*9)+(2*4)+(1*0)=196
196 % 10 = 6
So 289709-40-6 is a valid CAS Registry Number.
