869554-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 869554-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,5,5 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 869554-52:
(8*8)+(7*6)+(6*9)+(5*5)+(4*5)+(3*4)+(2*5)+(1*2)=229
229 % 10 = 9
So 869554-52-9 is a valid CAS Registry Number.
