The CAS Registry Mumber 50899-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,8,9 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 50899-13:
(7*5)+(6*0)+(5*8)+(4*9)+(3*9)+(2*1)+(1*3)=143
143 % 10 = 3
So 50899-13-3 is a valid CAS Registry Number.
