1227680-44-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1227680-44-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,6,8 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1227680-44:
(9*1)+(8*2)+(7*2)+(6*7)+(5*6)+(4*8)+(3*0)+(2*4)+(1*4)=155
155 % 10 = 5
So 1227680-44-5 is a valid CAS Registry Number.
