1202655-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1202655-18-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,6,5 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1202655-18:
(9*1)+(8*2)+(7*0)+(6*2)+(5*6)+(4*5)+(3*5)+(2*1)+(1*8)=112
112 % 10 = 2
So 1202655-18-2 is a valid CAS Registry Number.
