90841-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90841-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,4 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90841-23:
(7*9)+(6*0)+(5*8)+(4*4)+(3*1)+(2*2)+(1*3)=129
129 % 10 = 9
So 90841-23-9 is a valid CAS Registry Number.
