853569-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 853569-54-7 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, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 853569-54:
(8*8)+(7*5)+(6*3)+(5*5)+(4*6)+(3*9)+(2*5)+(1*4)=207
207 % 10 = 7
So 853569-54-7 is a valid CAS Registry Number.
