Check Digit Verification of cas no
The CAS Registry Mumber 164076-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,0,7 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 164076-17:
(8*1)+(7*6)+(6*4)+(5*0)+(4*7)+(3*6)+(2*1)+(1*7)=129
129 % 10 = 9
So 164076-17-9 is a valid CAS Registry Number.
