1009808-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1009808-81-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,9,8,0 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1009808-81:
(9*1)+(8*0)+(7*0)+(6*9)+(5*8)+(4*0)+(3*8)+(2*8)+(1*1)=144
144 % 10 = 4
So 1009808-81-4 is a valid CAS Registry Number.
