The CAS Registry Mumber 155781-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,7,8 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 155781-67:
(8*1)+(7*5)+(6*5)+(5*7)+(4*8)+(3*1)+(2*6)+(1*7)=162
162 % 10 = 2
So 155781-67-2 is a valid CAS Registry Number.
