1417565-87-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1417565-87-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,5,6 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1417565-87:
(9*1)+(8*4)+(7*1)+(6*7)+(5*5)+(4*6)+(3*5)+(2*8)+(1*7)=177
177 % 10 = 7
So 1417565-87-7 is a valid CAS Registry Number.
