The CAS Registry Mumber 1320-07-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1320-07:
(6*1)+(5*3)+(4*2)+(3*0)+(2*0)+(1*7)=36
36 % 10 = 6
So 1320-07-6 is a valid CAS Registry Number.
