158587-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158587-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,5,8 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158587-55:
(8*1)+(7*5)+(6*8)+(5*5)+(4*8)+(3*7)+(2*5)+(1*5)=184
184 % 10 = 4
So 158587-55-4 is a valid CAS Registry Number.
