881693-14-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 881693-14-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,6,9 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 881693-14:
(8*8)+(7*8)+(6*1)+(5*6)+(4*9)+(3*3)+(2*1)+(1*4)=207
207 % 10 = 7
So 881693-14-7 is a valid CAS Registry Number.
