The CAS Registry Mumber 7726-78-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,2 and 6 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 7726-78: (6*7)+(5*7)+(4*2)+(3*6)+(2*7)+(1*8)=125 125 % 10 = 5 So 7726-78-5 is a valid CAS Registry Number.
