The CAS Registry Mumber 141357-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,3,5 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141357-54:
(8*1)+(7*4)+(6*1)+(5*3)+(4*5)+(3*7)+(2*5)+(1*4)=112
112 % 10 = 2
So 141357-54-2 is a valid CAS Registry Number.
