The CAS Registry Mumber 21885-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,8 and 5 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 21885-39: (7*2)+(6*1)+(5*8)+(4*8)+(3*5)+(2*3)+(1*9)=122 122 % 10 = 2 So 21885-39-2 is a valid CAS Registry Number.
