Check Digit Verification of cas no
The CAS Registry Mumber 72705-26-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,0 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 72705-26:
(7*7)+(6*2)+(5*7)+(4*0)+(3*5)+(2*2)+(1*6)=121
121 % 10 = 1
So 72705-26-1 is a valid CAS Registry Number.
