Check Digit Verification of cas no
The CAS Registry Mumber 52771-99-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,7,7 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52771-99:
(7*5)+(6*2)+(5*7)+(4*7)+(3*1)+(2*9)+(1*9)=140
140 % 10 = 0
So 52771-99-0 is a valid CAS Registry Number.
