Check Digit Verification of cas no
The CAS Registry Mumber 6407-99-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6407-99:
(6*6)+(5*4)+(4*0)+(3*7)+(2*9)+(1*9)=104
104 % 10 = 4
So 6407-99-4 is a valid CAS Registry Number.
