1211318-74-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1211318-74-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,1,3,1 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1211318-74:
(9*1)+(8*2)+(7*1)+(6*1)+(5*3)+(4*1)+(3*8)+(2*7)+(1*4)=99
99 % 10 = 9
So 1211318-74-9 is a valid CAS Registry Number.
