321968-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 321968-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,9,6 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 321968-49:
(8*3)+(7*2)+(6*1)+(5*9)+(4*6)+(3*8)+(2*4)+(1*9)=154
154 % 10 = 4
So 321968-49-4 is a valid CAS Registry Number.
