873555-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 873555-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,5,5 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 873555-40:
(8*8)+(7*7)+(6*3)+(5*5)+(4*5)+(3*5)+(2*4)+(1*0)=199
199 % 10 = 9
So 873555-40-9 is a valid CAS Registry Number.
