219754-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219754-45-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,5 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219754-45:
(8*2)+(7*1)+(6*9)+(5*7)+(4*5)+(3*4)+(2*4)+(1*5)=157
157 % 10 = 7
So 219754-45-7 is a valid CAS Registry Number.
