4-5Check Digit Verification of cas no
The CAS Registry Mumber 6369-28-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,6 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.Calculate Digit Verification of CAS Registry Number 6369-28:
(6*6)+(5*3)+(4*6)+(3*9)+(2*2)+(1*8)=114
114 % 10 = 4
So 6369-28-4 is a valid CAS Registry Number.
