The CAS Registry Mumber 2809-37-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,0 and 9 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 2809-37: (6*2)+(5*8)+(4*0)+(3*9)+(2*3)+(1*7)=92 92 % 10 = 2 So 2809-37-2 is a valid CAS Registry Number.
