1417187-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1417187-31-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,1,8 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1417187-31:
(9*1)+(8*4)+(7*1)+(6*7)+(5*1)+(4*8)+(3*7)+(2*3)+(1*1)=155
155 % 10 = 5
So 1417187-31-5 is a valid CAS Registry Number.
