168640-85-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 168640-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,6,4 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 168640-85:
(8*1)+(7*6)+(6*8)+(5*6)+(4*4)+(3*0)+(2*8)+(1*5)=165
165 % 10 = 5
So 168640-85-5 is a valid CAS Registry Number.
