Check Digit Verification of cas no
The CAS Registry Mumber 183428-15-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,4,2 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 183428-15:
(8*1)+(7*8)+(6*3)+(5*4)+(4*2)+(3*8)+(2*1)+(1*5)=141
141 % 10 = 1
