157488-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157488-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,8 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 157488-87:
(8*1)+(7*5)+(6*7)+(5*4)+(4*8)+(3*8)+(2*8)+(1*7)=184
184 % 10 = 4
So 157488-87-4 is a valid CAS Registry Number.
