881927-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 881927-39-5 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, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 881927-39:
(8*8)+(7*8)+(6*1)+(5*9)+(4*2)+(3*7)+(2*3)+(1*9)=215
215 % 10 = 5
So 881927-39-5 is a valid CAS Registry Number.
