883971-58-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 883971-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,3,9,7 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 883971-58:
(8*8)+(7*8)+(6*3)+(5*9)+(4*7)+(3*1)+(2*5)+(1*8)=232
232 % 10 = 2
So 883971-58-2 is a valid CAS Registry Number.
