Check Digit Verification of cas no
The CAS Registry Mumber 6487-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,8 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6487-05:
(6*6)+(5*4)+(4*8)+(3*7)+(2*0)+(1*5)=114
114 % 10 = 4
So 6487-05-4 is a valid CAS Registry Number.
