109278-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109278-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,7 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109278-33:
(8*1)+(7*0)+(6*9)+(5*2)+(4*7)+(3*8)+(2*3)+(1*3)=133
133 % 10 = 3
So 109278-33-3 is a valid CAS Registry Number.
