Check Digit Verification of cas no
The CAS Registry Mumber 148842-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,8,4 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 148842-83:
(8*1)+(7*4)+(6*8)+(5*8)+(4*4)+(3*2)+(2*8)+(1*3)=165
165 % 10 = 5
So 148842-83-5 is a valid CAS Registry Number.
