1206248-51-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1206248-51-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,6,2,4 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1206248-51:
(9*1)+(8*2)+(7*0)+(6*6)+(5*2)+(4*4)+(3*8)+(2*5)+(1*1)=122
122 % 10 = 2
So 1206248-51-2 is a valid CAS Registry Number.
