151982-21-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151982-21-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,9,8 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 151982-21:
(8*1)+(7*5)+(6*1)+(5*9)+(4*8)+(3*2)+(2*2)+(1*1)=137
137 % 10 = 7
So 151982-21-7 is a valid CAS Registry Number.
