2Check Digit Verification of cas no
The CAS Registry Mumber 6599-18-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,9 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.Calculate Digit Verification of CAS Registry Number 6599-18:
(6*6)+(5*5)+(4*9)+(3*9)+(2*1)+(1*8)=134
134 % 10 = 4
So 6599-18-4 is a valid CAS Registry Number.
