The CAS Registry Mumber 71838-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,3 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.Calculate Digit Verification of CAS Registry Number 71838-95:
(7*7)+(6*1)+(5*8)+(4*3)+(3*8)+(2*9)+(1*5)=154
154 % 10 = 4
So 71838-95-4 is a valid CAS Registry Number.
