1256550-93-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1256550-93-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,5,5 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1256550-93:
(9*1)+(8*2)+(7*5)+(6*6)+(5*5)+(4*5)+(3*0)+(2*9)+(1*3)=162
162 % 10 = 2
So 1256550-93-2 is a valid CAS Registry Number.
