Check Digit Verification of cas no
The CAS Registry Mumber 139519-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,1 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139519-71:
(8*1)+(7*3)+(6*9)+(5*5)+(4*1)+(3*9)+(2*7)+(1*1)=154
154 % 10 = 4
