149883-42-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 149883-42-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,8,8 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 149883-42:
(8*1)+(7*4)+(6*9)+(5*8)+(4*8)+(3*3)+(2*4)+(1*2)=181
181 % 10 = 1
So 149883-42-1 is a valid CAS Registry Number.
