1263056-82-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1263056-82-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,0,5 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1263056-82:
(9*1)+(8*2)+(7*6)+(6*3)+(5*0)+(4*5)+(3*6)+(2*8)+(1*2)=141
141 % 10 = 1
So 1263056-82-1 is a valid CAS Registry Number.
