863638-71-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 863638-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,6,3 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 863638-71:
(8*8)+(7*6)+(6*3)+(5*6)+(4*3)+(3*8)+(2*7)+(1*1)=205
205 % 10 = 5
So 863638-71-5 is a valid CAS Registry Number.
