151521-94-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151521-94-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,5,2 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 151521-94:
(8*1)+(7*5)+(6*1)+(5*5)+(4*2)+(3*1)+(2*9)+(1*4)=107
107 % 10 = 7
So 151521-94-7 is a valid CAS Registry Number.
