87970-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87970-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,7 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87970-52:
(7*8)+(6*7)+(5*9)+(4*7)+(3*0)+(2*5)+(1*2)=183
183 % 10 = 3
So 87970-52-3 is a valid CAS Registry Number.
