887906-92-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 887906-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,9,0 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 887906-92:
(8*8)+(7*8)+(6*7)+(5*9)+(4*0)+(3*6)+(2*9)+(1*2)=245
245 % 10 = 5
So 887906-92-5 is a valid CAS Registry Number.
