Check Digit Verification of cas no
The CAS Registry Mumber 149820-65-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,8,2 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 149820-65:
(8*1)+(7*4)+(6*9)+(5*8)+(4*2)+(3*0)+(2*6)+(1*5)=155
155 % 10 = 5
So 149820-65-5 is a valid CAS Registry Number.
