917987-41-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 917987-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,9,8 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 917987-41:
(8*9)+(7*1)+(6*7)+(5*9)+(4*8)+(3*7)+(2*4)+(1*1)=228
228 % 10 = 8
So 917987-41-8 is a valid CAS Registry Number.
