886993-19-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 886993-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,6,9,9 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 886993-19:
(8*8)+(7*8)+(6*6)+(5*9)+(4*9)+(3*3)+(2*1)+(1*9)=257
257 % 10 = 7
So 886993-19-7 is a valid CAS Registry Number.
