855127-42-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 855127-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,1,2 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 855127-42:
(8*8)+(7*5)+(6*5)+(5*1)+(4*2)+(3*7)+(2*4)+(1*2)=173
173 % 10 = 3
So 855127-42-3 is a valid CAS Registry Number.
