1268823-09-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1268823-09-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,8,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1268823-09:
(9*1)+(8*2)+(7*6)+(6*8)+(5*8)+(4*2)+(3*3)+(2*0)+(1*9)=181
181 % 10 = 1
So 1268823-09-1 is a valid CAS Registry Number.
