1261029-03-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1261029-03-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,1,0,2 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1261029-03:
(9*1)+(8*2)+(7*6)+(6*1)+(5*0)+(4*2)+(3*9)+(2*0)+(1*3)=111
111 % 10 = 1
So 1261029-03-1 is a valid CAS Registry Number.
