Check Digit Verification of cas no
The CAS Registry Mumber 10126-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10126-91:
(7*1)+(6*0)+(5*1)+(4*2)+(3*6)+(2*9)+(1*1)=57
57 % 10 = 7
So 10126-91-7 is a valid CAS Registry Number.
