212560-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 212560-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,5,6 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 212560-68:
(8*2)+(7*1)+(6*2)+(5*5)+(4*6)+(3*0)+(2*6)+(1*8)=104
104 % 10 = 4
So 212560-68-4 is a valid CAS Registry Number.
