Check Digit Verification of cas no
The CAS Registry Mumber 919076-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,9,0,7 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 919076-97:
(8*9)+(7*1)+(6*9)+(5*0)+(4*7)+(3*6)+(2*9)+(1*7)=204
204 % 10 = 4
So 919076-97-4 is a valid CAS Registry Number.
