Check Digit Verification of cas no
The CAS Registry Mumber 5863-95-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,6 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5863-95:
(6*5)+(5*8)+(4*6)+(3*3)+(2*9)+(1*5)=126
126 % 10 = 6
So 5863-95-6 is a valid CAS Registry Number.
