1442648-11-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1442648-11-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,2,6,4 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1442648-11:
(9*1)+(8*4)+(7*4)+(6*2)+(5*6)+(4*4)+(3*8)+(2*1)+(1*1)=154
154 % 10 = 4
So 1442648-11-4 is a valid CAS Registry Number.
