Check Digit Verification of cas no
The CAS Registry Mumber 257630-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,6,3 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 257630-75:
(8*2)+(7*5)+(6*7)+(5*6)+(4*3)+(3*0)+(2*7)+(1*5)=154
154 % 10 = 4
So 257630-75-4 is a valid CAS Registry Number.
