900188-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 900188-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,1,8 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 900188-22:
(8*9)+(7*0)+(6*0)+(5*1)+(4*8)+(3*8)+(2*2)+(1*2)=139
139 % 10 = 9
So 900188-22-9 is a valid CAS Registry Number.
