The CAS Registry Mumber 3056-93-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,5 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3056-93:
(6*3)+(5*0)+(4*5)+(3*6)+(2*9)+(1*3)=77
77 % 10 = 7
So 3056-93-7 is a valid CAS Registry Number.
