251955-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 251955-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,9,5 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 251955-49:
(8*2)+(7*5)+(6*1)+(5*9)+(4*5)+(3*5)+(2*4)+(1*9)=154
154 % 10 = 4
So 251955-49-4 is a valid CAS Registry Number.
