70189-62-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70189-62-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,8 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 70189-62:
(7*7)+(6*0)+(5*1)+(4*8)+(3*9)+(2*6)+(1*2)=127
127 % 10 = 7
So 70189-62-7 is a valid CAS Registry Number.
