1292838-28-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1292838-28-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,8,3 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1292838-28:
(9*1)+(8*2)+(7*9)+(6*2)+(5*8)+(4*3)+(3*8)+(2*2)+(1*8)=188
188 % 10 = 8
So 1292838-28-8 is a valid CAS Registry Number.
