148676-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 148676-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,6,7 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 148676-91:
(8*1)+(7*4)+(6*8)+(5*6)+(4*7)+(3*6)+(2*9)+(1*1)=179
179 % 10 = 9
So 148676-91-9 is a valid CAS Registry Number.
