Check Digit Verification of cas no
The CAS Registry Mumber 684250-09-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,4,2,5 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 684250-09:
(8*6)+(7*8)+(6*4)+(5*2)+(4*5)+(3*0)+(2*0)+(1*9)=167
167 % 10 = 7
So 684250-09-7 is a valid CAS Registry Number.
