Check Digit Verification of cas no
The CAS Registry Mumber 50263-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,2,6 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 50263-91:
(7*5)+(6*0)+(5*2)+(4*6)+(3*3)+(2*9)+(1*1)=97
97 % 10 = 7
So 50263-91-7 is a valid CAS Registry Number.
