863640-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 863640-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,6,4 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 863640-40:
(8*8)+(7*6)+(6*3)+(5*6)+(4*4)+(3*0)+(2*4)+(1*0)=178
178 % 10 = 8
So 863640-40-8 is a valid CAS Registry Number.
