The CAS Registry Mumber 28737-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,3 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28737-01:
(7*2)+(6*8)+(5*7)+(4*3)+(3*7)+(2*0)+(1*1)=131
131 % 10 = 1
So 28737-01-1 is a valid CAS Registry Number.
