Check Digit Verification of cas no
The CAS Registry Mumber 257621-06-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,6,2 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 257621-06:
(8*2)+(7*5)+(6*7)+(5*6)+(4*2)+(3*1)+(2*0)+(1*6)=140
140 % 10 = 0
So 257621-06-0 is a valid CAS Registry Number.
