623905-90-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 623905-90-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,9,0 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 623905-90:
(8*6)+(7*2)+(6*3)+(5*9)+(4*0)+(3*5)+(2*9)+(1*0)=158
158 % 10 = 8
So 623905-90-8 is a valid CAS Registry Number.
