690993-31-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 690993-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,9,9 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 690993-31:
(8*6)+(7*9)+(6*0)+(5*9)+(4*9)+(3*3)+(2*3)+(1*1)=208
208 % 10 = 8
So 690993-31-8 is a valid CAS Registry Number.
