The CAS Registry Mumber 1201-16-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 1 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1201-16: (6*1)+(5*2)+(4*0)+(3*1)+(2*1)+(1*6)=27 27 % 10 = 7 So 1201-16-7 is a valid CAS Registry Number.
