Check Digit Verification of cas no
The CAS Registry Mumber 29726-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,7,2 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 29726-21:
(7*2)+(6*9)+(5*7)+(4*2)+(3*6)+(2*2)+(1*1)=134
134 % 10 = 4
So 29726-21-4 is a valid CAS Registry Number.
