The CAS Registry Mumber 155608-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,0 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 155608-76:
(8*1)+(7*5)+(6*5)+(5*6)+(4*0)+(3*8)+(2*7)+(1*6)=147
147 % 10 = 7
So 155608-76-7 is a valid CAS Registry Number.
