Check Digit Verification of cas no
The CAS Registry Mumber 168569-04-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,5,6 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 168569-04:
(8*1)+(7*6)+(6*8)+(5*5)+(4*6)+(3*9)+(2*0)+(1*4)=178
178 % 10 = 8
So 168569-04-8 is a valid CAS Registry Number.
