1243986-17-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1243986-17-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,9,8 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1243986-17:
(9*1)+(8*2)+(7*4)+(6*3)+(5*9)+(4*8)+(3*6)+(2*1)+(1*7)=175
175 % 10 = 5
So 1243986-17-5 is a valid CAS Registry Number.
