1227732-28-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1227732-28-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,7,3 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1227732-28:
(9*1)+(8*2)+(7*2)+(6*7)+(5*7)+(4*3)+(3*2)+(2*2)+(1*8)=146
146 % 10 = 6
So 1227732-28-6 is a valid CAS Registry Number.
