The CAS Registry Mumber 853015-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,0,1 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 853015-67:
(8*8)+(7*5)+(6*3)+(5*0)+(4*1)+(3*5)+(2*6)+(1*7)=155
155 % 10 = 5
So 853015-67-5 is a valid CAS Registry Number.
