2Check Digit Verification of cas no
The CAS Registry Mumber 6405-98-7 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 5 respectively; the second part has 2 digits, 9 and 8 respectively.Calculate Digit Verification of CAS Registry Number 6405-98:
(6*6)+(5*4)+(4*0)+(3*5)+(2*9)+(1*8)=97
97 % 10 = 7
So 6405-98-7 is a valid CAS Registry Number.
