923947-18-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 923947-18-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,3,9,4 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 923947-18:
(8*9)+(7*2)+(6*3)+(5*9)+(4*4)+(3*7)+(2*1)+(1*8)=196
196 % 10 = 6
So 923947-18-6 is a valid CAS Registry Number.
