78994-21-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78994-21-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,9 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78994-21:
(7*7)+(6*8)+(5*9)+(4*9)+(3*4)+(2*2)+(1*1)=195
195 % 10 = 5
So 78994-21-5 is a valid CAS Registry Number.
