937040-98-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 937040-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,7,0,4 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 937040-98:
(8*9)+(7*3)+(6*7)+(5*0)+(4*4)+(3*0)+(2*9)+(1*8)=177
177 % 10 = 7
So 937040-98-7 is a valid CAS Registry Number.
