Check Digit Verification of cas no
The CAS Registry Mumber 3244-97-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,4 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3244-97:
(6*3)+(5*2)+(4*4)+(3*4)+(2*9)+(1*7)=81
81 % 10 = 1
So 3244-97-1 is a valid CAS Registry Number.
