909850-41-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909850-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,8,5 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 909850-41:
(8*9)+(7*0)+(6*9)+(5*8)+(4*5)+(3*0)+(2*4)+(1*1)=195
195 % 10 = 5
So 909850-41-5 is a valid CAS Registry Number.
