89947-87-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89947-87-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,4 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89947-87:
(7*8)+(6*9)+(5*9)+(4*4)+(3*7)+(2*8)+(1*7)=215
215 % 10 = 5
So 89947-87-5 is a valid CAS Registry Number.
