1268854-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1268854-71-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,8,5 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1268854-71:
(9*1)+(8*2)+(7*6)+(6*8)+(5*8)+(4*5)+(3*4)+(2*7)+(1*1)=202
202 % 10 = 2
So 1268854-71-2 is a valid CAS Registry Number.
