Check Digit Verification of cas no
The CAS Registry Mumber 289507-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,5,0 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 289507-34:
(8*2)+(7*8)+(6*9)+(5*5)+(4*0)+(3*7)+(2*3)+(1*4)=182
182 % 10 = 2
So 289507-34-2 is a valid CAS Registry Number.
