The CAS Registry Mumber 130276-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,7 and 6 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 130276-66: (8*1)+(7*3)+(6*0)+(5*2)+(4*7)+(3*6)+(2*6)+(1*6)=103 103 % 10 = 3 So 130276-66-3 is a valid CAS Registry Number.
