Check Digit Verification of cas no
The CAS Registry Mumber 426839-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,6,8,3 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 426839-90:
(8*4)+(7*2)+(6*6)+(5*8)+(4*3)+(3*9)+(2*9)+(1*0)=179
179 % 10 = 9
So 426839-90-9 is a valid CAS Registry Number.
