157553-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157553-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,5,5 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 157553-92:
(8*1)+(7*5)+(6*7)+(5*5)+(4*5)+(3*3)+(2*9)+(1*2)=159
