290820-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 290820-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,8,2 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 290820-89:
(8*2)+(7*9)+(6*0)+(5*8)+(4*2)+(3*0)+(2*8)+(1*9)=152
152 % 10 = 2
So 290820-89-2 is a valid CAS Registry Number.
