853569-39-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 853569-39-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,5,6 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 853569-39:
(8*8)+(7*5)+(6*3)+(5*5)+(4*6)+(3*9)+(2*3)+(1*9)=208
208 % 10 = 8
So 853569-39-8 is a valid CAS Registry Number.
