The CAS Registry Mumber 7729-39-7 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 9 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 7729-39: (6*7)+(5*7)+(4*2)+(3*9)+(2*3)+(1*9)=127 127 % 10 = 7 So 7729-39-7 is a valid CAS Registry Number.
