31154-87-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31154-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,5 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.Calculate Digit Verification of CAS Registry Number 31154-87:
(7*3)+(6*1)+(5*1)+(4*5)+(3*4)+(2*8)+(1*7)=87
87 % 10 = 7
So 31154-87-7 is a valid CAS Registry Number.
