The CAS Registry Mumber 12156-40-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,5 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12156-40:
(7*1)+(6*2)+(5*1)+(4*5)+(3*6)+(2*4)+(1*0)=70
70 % 10 = 0
So 12156-40-0 is a valid CAS Registry Number.
