The CAS Registry Mumber 36206-71-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,2,0 and 6 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 36206-71: (7*3)+(6*6)+(5*2)+(4*0)+(3*6)+(2*7)+(1*1)=100 100 % 10 = 0 So 36206-71-0 is a valid CAS Registry Number.
