Check Digit Verification of cas no
The CAS Registry Mumber 12768-78-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,7,6 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12768-78:
(7*1)+(6*2)+(5*7)+(4*6)+(3*8)+(2*7)+(1*8)=124
124 % 10 = 4
So 12768-78-4 is a valid CAS Registry Number.
