Check Digit Verification of cas no
The CAS Registry Mumber 99478-07-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,7 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99478-07:
(7*9)+(6*9)+(5*4)+(4*7)+(3*8)+(2*0)+(1*7)=196
196 % 10 = 6
So 99478-07-6 is a valid CAS Registry Number.
