Check Digit Verification of cas no
The CAS Registry Mumber 20736-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,3 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20736-29:
(7*2)+(6*0)+(5*7)+(4*3)+(3*6)+(2*2)+(1*9)=92
92 % 10 = 2
So 20736-29-2 is a valid CAS Registry Number.
