156899-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156899-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,8,9 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 156899-89:
(8*1)+(7*5)+(6*6)+(5*8)+(4*9)+(3*9)+(2*8)+(1*9)=207
207 % 10 = 7
So 156899-89-7 is a valid CAS Registry Number.
