220998-37-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 220998-37-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,9,9 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 220998-37:
(8*2)+(7*2)+(6*0)+(5*9)+(4*9)+(3*8)+(2*3)+(1*7)=148
148 % 10 = 8
So 220998-37-8 is a valid CAS Registry Number.
