855594-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 855594-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,5,9 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 855594-77:
(8*8)+(7*5)+(6*5)+(5*5)+(4*9)+(3*4)+(2*7)+(1*7)=223
223 % 10 = 3
So 855594-77-3 is a valid CAS Registry Number.
