1280722-82-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1280722-82-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,7,2 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1280722-82:
(9*1)+(8*2)+(7*8)+(6*0)+(5*7)+(4*2)+(3*2)+(2*8)+(1*2)=148
148 % 10 = 8
So 1280722-82-8 is a valid CAS Registry Number.
