Check Digit Verification of cas no
The CAS Registry Mumber 12768-89-7 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, 8 and 9 respectively.Calculate Digit Verification of CAS Registry Number 12768-89:
(7*1)+(6*2)+(5*7)+(4*6)+(3*8)+(2*8)+(1*9)=127
127 % 10 = 7
So 12768-89-7 is a valid CAS Registry Number.
