881927-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 881927-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,9,2 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 881927-41:
(8*8)+(7*8)+(6*1)+(5*9)+(4*2)+(3*7)+(2*4)+(1*1)=209
209 % 10 = 9
So 881927-41-9 is a valid CAS Registry Number.
