78636-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78636-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,3 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78636-40:
(7*7)+(6*8)+(5*6)+(4*3)+(3*6)+(2*4)+(1*0)=165
165 % 10 = 5
So 78636-40-5 is a valid CAS Registry Number.
