Check Digit Verification of cas no
The CAS Registry Mumber 73057-37-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,5 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73057-37:
(7*7)+(6*3)+(5*0)+(4*5)+(3*7)+(2*3)+(1*7)=121
121 % 10 = 1
So 73057-37-1 is a valid CAS Registry Number.
