Check Digit Verification of cas no
The CAS Registry Mumber 254966-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,9,6 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 254966-97:
(8*2)+(7*5)+(6*4)+(5*9)+(4*6)+(3*6)+(2*9)+(1*7)=187
187 % 10 = 7
So 254966-97-7 is a valid CAS Registry Number.
