1221174-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1221174-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,1,7 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1221174-52:
(9*1)+(8*2)+(7*2)+(6*1)+(5*1)+(4*7)+(3*4)+(2*5)+(1*2)=102
102 % 10 = 2
So 1221174-52-2 is a valid CAS Registry Number.
