Check Digit Verification of cas no
The CAS Registry Mumber 161678-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,6,7 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 161678-07:
(8*1)+(7*6)+(6*1)+(5*6)+(4*7)+(3*8)+(2*0)+(1*7)=145
145 % 10 = 5
So 161678-07-5 is a valid CAS Registry Number.
