1080649-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1080649-22-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,0,6,4 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1080649-22:
(9*1)+(8*0)+(7*8)+(6*0)+(5*6)+(4*4)+(3*9)+(2*2)+(1*2)=144
144 % 10 = 4
So 1080649-22-4 is a valid CAS Registry Number.
