1227271-04-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1227271-04-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,2,7 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1227271-04:
(9*1)+(8*2)+(7*2)+(6*7)+(5*2)+(4*7)+(3*1)+(2*0)+(1*4)=126
126 % 10 = 6
So 1227271-04-6 is a valid CAS Registry Number.
