917878-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 917878-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,8,7 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 917878-56:
(8*9)+(7*1)+(6*7)+(5*8)+(4*7)+(3*8)+(2*5)+(1*6)=229
229 % 10 = 9
So 917878-56-9 is a valid CAS Registry Number.
