155899-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155899-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,9 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 155899-45:
(8*1)+(7*5)+(6*5)+(5*8)+(4*9)+(3*9)+(2*4)+(1*5)=189
189 % 10 = 9
So 155899-45-9 is a valid CAS Registry Number.
