2-3Check Digit Verification of cas no
The CAS Registry Mumber 2896-76-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,9 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.Calculate Digit Verification of CAS Registry Number 2896-76:
(6*2)+(5*8)+(4*9)+(3*6)+(2*7)+(1*6)=126
126 % 10 = 6
So 2896-76-6 is a valid CAS Registry Number.
