1256244-39-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1256244-39-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,2,4 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1256244-39:
(9*1)+(8*2)+(7*5)+(6*6)+(5*2)+(4*4)+(3*4)+(2*3)+(1*9)=149
149 % 10 = 9
So 1256244-39-9 is a valid CAS Registry Number.
