The CAS Registry Mumber 135673-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,7 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135673-08:
(8*1)+(7*3)+(6*5)+(5*6)+(4*7)+(3*3)+(2*0)+(1*8)=134
134 % 10 = 4
So 135673-08-4 is a valid CAS Registry Number.
