The CAS Registry Mumber 72853-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,5 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72853-37:
(7*7)+(6*2)+(5*8)+(4*5)+(3*3)+(2*3)+(1*7)=143
143 % 10 = 3
So 72853-37-3 is a valid CAS Registry Number.
