1202181-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1202181-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,1,8 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1202181-40:
(9*1)+(8*2)+(7*0)+(6*2)+(5*1)+(4*8)+(3*1)+(2*4)+(1*0)=85
85 % 10 = 5
So 1202181-40-5 is a valid CAS Registry Number.
