The CAS Registry Mumber 957257-38-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,2,5 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 957257-38:
(8*9)+(7*5)+(6*7)+(5*2)+(4*5)+(3*7)+(2*3)+(1*8)=214
214 % 10 = 4
So 957257-38-4 is a valid CAS Registry Number.
