871948-92-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871948-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,9,4 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 871948-92:
(8*8)+(7*7)+(6*1)+(5*9)+(4*4)+(3*8)+(2*9)+(1*2)=224
224 % 10 = 4
So 871948-92-4 is a valid CAS Registry Number.
