853569-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 853569-40-1 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, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 853569-40:
(8*8)+(7*5)+(6*3)+(5*5)+(4*6)+(3*9)+(2*4)+(1*0)=201
201 % 10 = 1
So 853569-40-1 is a valid CAS Registry Number.
